Routing Optimization in mobile ad hoc networks is an ever-demanding task. Mobile ad hoc networks are highly dynamic topology natured and hence several routing protocols meet the challenge of link quality, delay and energy conscious routing. This paper proposes a link quality, delay and energy conscious routing approach based on ant colony optimization. Based on the estimated link quality, delay and residual energy of the nearby nodes, Adaptive node stability (ANS) mechanism is mathematically modeled to make the routing strategy. LQDEARP selects the efficient node based on the ANS mechanism and sends the data packets through that node. Simulation results proved that LQDEARP reduces delay and energy consumption and increases packet delivery ratio than that of the AODV and DECRP protocol.

In mobile ad hoc networks, nodes are mobile and have limited energy resource that can quickly deplete due to the multi-hop routing activities, which may gradually lead to an un-operational network. In the past decades, the hunt for a reliable and energy-efficient MANET routing protocol has been extensively researched. In this thesis, a novel routing scheme for MANETs (so-called MAntNet) has been proposed, which is based on the AntNet approach. Precisely, the AntNet algorithm is modified in such a way that the routing decisions are facilitated based on the available nodes energy. Additionally, some energy-aware conditions are introduced in MAntNet and replicated in the conventional AODV routing protocol for MANETs. The resulting energy-aware M-AntNet (E-MAntNet) and energy-aware AODV(E-AODV) are analyzed using NS2 simulations. The results show that E-MAntNet performs significantly better than MAntNet and E-AODV both in terms of network residual energy and number of established connections in the network.

Mobile Ad Hoc Networks (MANETs) are wireless networks which comprise of mobile nodes with limited energy resources. Every node cooperates to perform routing and expends energy on a frequent basis. Nodes are mobile thus link breakages are common and new routes need to be established quickly. Traditional routing protocols tend to find shortest routes to destination providing best-effort delivery service. However due to limited energy and bandwidth resources shortest path routes may not suffice and may usually degrade the performance of the network. In this paper an Energy aware Node Disjoint routing technique END-AODV is proposed that is based on the traditional AODV protocol. The technique designed is based on the argument that node disjoint multipath routing can conserve energy more efficiently as compared to link disjoint routing. Link Disjoint routing leads to overuse of a subset of nodes thus decreasing the overall network lifetime. The technique proposed incorporates energy drain rate metric to establish energy aware routes which are node disjoint in nature. Simulation results with ns2.34 simulator show efficiency of the proposed technique in terms of packet delivery ratio, average energy consumption per data bit delivered, network lifetime and average end to end delay.
