    Mobile Ad Hoc Network is a group of mobile nodes which can communicate with each other directly without infrastructure device. Most conventional protocols do not consider energy on route discovery. Route breaks may occur frequently since the energy of some intermediate nodes exhausts. This interrupts the packet forwarding. In this paper, we propose load distribution algorithm based on remaining energy of nodes to prolong network lifetime and load balancing. Simulation results show that our work can increase the number of remaining nodes in the network while maintaining high packet delivery ratio.

    In this paper, we present the impact of mobility on our scheme called Location-based Routing with Adaptive Request Zone (LoRAReZ). In LoRAReZ, the size of expected zone and request zone are set adaptively based on the distance between the source node and destination node. We evaluate the impact of mobility on the performance of LoRAReZ in terms of packet delivery fraction, routing overhead, end-to-end delay, throughput and power consumption by comparing with those of the traditional Ad Hoc On-Demand Distance Vector (AODV) and Modified Ad Hoc On-Demand Distance Vector (MAODV). The results show that LoRAReZ can provide the better performance than those of AODV and MAODV. © 2012 IEEE.

    Multi-hop AODV-2T

    Communication in Ad Hoc wireless network may generally be uncertain because the established route could be broken anytime. The major cause of link failures in Ad hoc wireless network is the dynamic movement of the mobile nodes themselves and the other might be battery running out. AODV-2T [9] is an improved AODV designed to compromise this problems by applying a conservative and circumspect concept. By investigating received RF signal and the battery power, AODV-2T could overcome the problem by preparing a backup route just-in-time before link breaking. This makes it is able to switch packet transmission to the backup route without any delay with a bit of additive overhead. Although AODV-2T performs rather well compared to the early proposed protocols [4, 11, 12, 14, 19] in term of overhead and number of route break but AODV-2T is not capable to construct a multi-hop backup route. On the assumption that Multi-hop backup route establishment might be more flexible and gives more chance of success in Ad hoc route maintenance, so we have extended AODV-2T to support multi-hop backup route. The improved protocol called Multi-hop AODV-2T was implemented into a NS-2 model. We simulated Multi-hop AODV-2T function and compared its route maintenance mechanism's performance with AODV and AODV-2T. The results have shown that Multi-hop AODV can reduce number of route break and packet loss obviously. © 2009 IEEE.
