PL-AOMDV: An Enhanced Energy Efficient Multipath Routing for MANETs

Multipath routing protocols are more prominent in mobile ad hoc networks (MANETs), as they beat certain impediments of single-path routing. Contrasted with single-path routing methodologies they have numerous points of interest in term of lower end-to-end delay, higher throughput, higher energy efficiency and network lifetime. Energy efficiency is essential prerequisites in numerous applications as nodes in MANETs are battery worked. In this paper, Power and Load Aware Ad-hoc On-demand Multipath Distance Vector Routing (PL-AOMDV) is presented. PL-AOMDV is a multipath routing protocol which chooses ways between source-destination pair in light of a consolidated cost function. The cost function is registered by considering remaining battery strength of a node and its present traffic. This article assesses the execution of PL-AOMDV by contrasting it with existing protocol AOMDV. Simulation results recommend that the proposed protocol has lower energy consumption, higher packet delivery ratio and throughput

A Review of the Energy Efficient and Secure Multicast Routing Protocols for Mobile Ad hoc Networks

This paper presents a thorough survey of recent work addressing energy efficient multicast routing protocols and secure multicast routing protocols in Mobile Ad hoc Networks (MANETs). There are so many issues and solutions which witness the need of energy management and security in ad hoc wireless networks. The objective of a multicast routing protocol for MANETs is to support the propagation of data from a sender to all the receivers of a multicast group while trying to use the available bandwidth efficiently in the presence of frequent topology changes. Multicasting can improve the efficiency of the wireless link when sending multiple copies of messages by exploiting the inherent broadcast property of wireless transmission. Secure multicast routing plays a significant role in MANETs. However, offering energy efficient and secure multicast routing is a difficult and challenging task. In recent years, various multicast routing protocols have been proposed for MANETs. These protocols have distinguishing features and use different mechanismsComment: 15 page

Fuzzy based load and energy aware multipath routing for mobile ad hoc networks

Routing is a challenging task in Mobile Ad hoc Networks (MANET) due to their dynamic topology and lack of central administration. As a consequence of un-predictable topology changes of such networks, routing protocols employed need to accurately capture the delay, load, available bandwidth and residual node energy at various locations of the network for effective energy and load balancing. This paper presents a fuzzy logic based scheme that ensures delay, load and energy aware routing to avoid congestion and minimise end-to-end delay in MANETs. In the proposed approach, forwarding delay, average load, available bandwidth and residual battery energy at a mobile node are given as inputs to a fuzzy inference engine to determine the traffic distribution possibility from that node based on the given fuzzy rules. Based on the output from the fuzzy system, traffic is distributed over fail-safe multiple routes to reduce the load at a congested node. Through simulation results, we show that our approach reduces end-to-end delay, packet drop and average energy consumption and increases packet delivery ratio for constant bit rate (CBR) traffic when compared with the popular Ad hoc On-demand Multipath Distance Vector (AOMDV) routing protocol
