Design and Implementation of ID Based MANET Autoconfiguration Protocol

Auto-configuration protocols are used for assignment of unique IP addresses to nodes in Mobile ad hoc networks. Without the assignment of unique IP addresses, service provisioning between the nodes is not possible. Such protocols use various heuristics to ensure the uniqueness in IP address assignment; such aspects increase the overall complexity in MANET system design. Moreover the overriding role of IP address as an ID in Application layer and Locator in routing space is a bottleneck in future wireless network (FWN) design. Contemporary FWN research is focusing on ID/Locator split concept designs. In this paper we propose an ID/Locator based architecture for MANETs which also solves               auto-configuration requirements for MANETs. Our proposed architecture is an adaptation from available ID/Locator split concepts for infrastructure oriented networks for usage in MANET context. The designed protocol uses identifiers for node identification, node discovery and traffic flow between end points. The protocol support provision for running contemporary IP oriented services. We have also verified various use cases of our proposed protocol through Linux based implementation

Comparative Study of Various Reactive MANET Protocols

Wireless ad hoc network acquired attention of research, as it does not require any infrastructure for its connectivity. So, it works independently with certain number of mobile nodes. The nodes used in the ad hoc are autonomous nodes which work as both the host and the route. The flexibility of nodes affects both the source and destination. Adaptive routing protocol establish specifically for the use of ad hoc environment that have at least one receiver .In this paper for the experimental purpose, Researcher studies about the adaptive routing protocol of the ad hoc network and compare its two protocol AODV which is a single path, loop free protocol while AOMDV uses multipath to communicate between single node and destination. Due to limited resources in MANETs the routing is vital issue

Performance Analysis and Comparison of Multiple Routing Protocols in a Large-Area, High Speed Mobile Node Ad Hoc Network

The U.S. Air Force is interested in developing a standard ad hoc framework using heavy aircraft to route data across large regions. The Zone Routing Protocol (ZRP) has the potential to provide seamless large-scale routing for DOD under the Joint Tactical Radio System program. The goal of this study is to determine if there is a difference between routing protocol performance when operating in a large-area MANET with high-speed mobile nodes. This study analyzes MANET performance when using reactive, proactive, and hybrid routing protocols, specifically AODV, DYMO, Fisheye, and ZRP. This analysis compares the performance of the four routing protocols under the same MANET conditions. Average end-to-end delay, number of packets received, and throughput are the performance metrics used. Reactive protocol performance is better than hybrid and proactive protocol performance in each metric. Average ETE delays are lower using AODV (1.17 secs) and DYMO (2.14 secs) than ZRP (201.9 secs) or Fisheye (169.7 secs). Number of packets received is higher using AODV (531.6) and DYMO (670.2) than ZRP (267.3) or Fisheye (186.3). Throughput is higher using AODV (66,500 bps) and DYMO (87,577 bps) than ZRP (33,659 bps) or Fisheye (23,630bps). The benefits of ZRP and Fisheye are not able to be taken advantage of in the MANET configurations modeled in this research using a heavy aircraft ad hoc framework

IDHOCNET-A Novel Protocol Stack and Architecture for Ad hoc Networks

Presently employed Internet Protocol (IP) stack possesses number of architectural problems. The issues like Dual/Overriding role of IP addresses, mobility, multi-homing etc are the limitations for the infrastructure oriented networks which even have support of Dynamic Host Configuration Protocol (DHCP), Domain Name System (DNS), Network Address Translation (NAT) servers, etc. Such issues are extremely complex to handle in the case of multi-hop wireless ad hoc networks which lack the support of any infrastructure component. The contemporary research direction for the improvement of present Internet architecture mainly focuses on the use of real identifiers instead of IP addresses for host identification in the network. However, the proposed architectures mostly discuss the infrastructure oriented network models and minimal research has been conducted in the direction of proposals for ad hoc networks.  In this paper we provide a thorough discussion on the practical usage issues of IP based ad hoc network implementation. In order to resolve the present limitations of ad hoc networks, we describe an implementation of a novel identifier based ad hoc network protocol stack and architecture known as IDHOCNET (Identifier based ad hoc network). The architecture proposes a novel paradigm of identifier based applications for multi-hop wireless ad hoc environment. The proposed system further provides backward compatibility to support co-existence with IP based applications. As a proof of concept, the architecture has been implemented on Linux platform with WiFi interfaces. Various practical scenarios with architectural insight are presented to demonstrate the practicability of the proposed approach

Avoiding Network Performance Degradation Problem in Zigbee

ABSTRACT: Zigbee is Associate in Nursing communication customary that is intended for Associate in Nursing low rate wireless personal space network, it's less price, less complexness and low power consumption in mobile device. Among the zigbee topologies, tree topologies are appropriate for low power and low price detector network as a result of is supports for power saving operation and even for the sunshine weight routing. Zigbee tree routing is IEEE 802.15.4 customary that is employed in several resources, applications and even within the restricted device. Zigbee tree routing doesn't offer any routing table and route discovery to send the packet from supply to the destination. In Zigbee tree routing, packet follows the tree topology that because the basic limitation and it doesn't offer the optimal(correct) routing path to destination .In this paper ,we planned the road tree routing(STR) protocol to decrease the routing price of ZTR with facilitate of neighbor table and conjointly scale back the overhead. The most plan is by employing a hierarchic addressing theme, the road tree routing calculate the remaining hops from discretionary supply to destination. By victimization mathematically analysis, prove that the one hop neighbor info increase overall network performance by requiring the routing path expeditiously and distributing the traffic load targeting the tree links

Hierarchical routing in MANETs using simple clustering

This thesis presents both a review of current MANET routing protocols and a new MANET routing algorithm. The routing protocols reviewed include representative samples from the three primary forms of routing found in MANETS: proactive routing, reactive routing and hybrid routing. Secure algorithms are given special treatment in the review. In addition several protocol enhancements are discussed. The proposed routing protocol is designed to support networks of a medium size, containing over 200 nodes but less than 3,000 nodes. The design is intentionally simple to allow ease of implementation in comparison with other MANET protocols that provide similar functionality
