Queue Length and Mobility aware Routing Protocol for Mobile Ad hoc Network

A mobile ad-hoc network (MANET) is different from other wireless networks in many ways. One of the key differences is that a MANET is a multihop wireless network,i.e., a routing path is composed of intermediate mobile nodes and wireless links connecting them. In this paper, heterogeneous Mobile Ad-hoc Networks (H-MANETs) are considered. H-MANETs are composed of nodes with different transmission range. We propose an improvement of AODV protocol called AMAODV (Adaptative Mobility aware AODV). This protocol is based on new metric combine more routing metrics (distance, relative velocity, queue length and hop count) between each node and one hop neighbor. Which permits to avoid losing route. Through the simulation, it is confirmed that this improvement has higher packet delivery ratio and less average end-to-end delay than basic AODV protocol.

A Routing Protocol Based on Mobility Prediction for Mobile Ad Hoc Networks

In Mobile Ad hoc Networks (MANETs), where nodes have limited transmitting power, the transmission is typically multi-hop. The network topology changes frequently due to the unpredictable movement of mobile nodes because each node is free to move arbitrarily with different speeds. Thus, when one node enters in the transmission range of another node a link between those two nodes is established, and an existent link is broken when either node is out of the transmission range of the other. We refer as link duration, the time interval during in which the link still established. This paper presents a novel mobility metric for mobile ad hoc networks, called link duration (LD) that measures the stability of an active link. This mobility metric is introduced to represent relative mobility between nodes in multi-hop distance
