Abstract

A set of mobile hosts or nodes that form a dynamic topology which is ad hoc in nature is called MANET. There are several challenges while designing a routing protocol for MANET due to the limited energy, less processing capability, fewer resources and dynamic environmental changes. Most of the existing energy efficient protocols focuses on choosing a route or path through the nodes with maximum residual energy and distribute a network traffic blindly among generated paths. Network congestion caused due to traffic and node packet carrying capability based on its remaining energy are not considered which leads to increasing number of dead nodes and result in more energy depletion. Hence we have proposed a Power Aware Load Balancing Multipath Routing Protocol (PALBMRP) which selects an optimal energy efficient route based on multiple parameters i.e. residual energy, delay, congestion and hop count and perform load balancing by considering nodes minimal residual energy to transmit packets according to its capacity. The simulation shows the proposed protocol reduced overall energy consumption up to 9%, increased packet delivery ratio up to 12%, and reduced end to end delay up to 3%, compared to AOMDV and LBMMRE-AOMDV [1].

Abstract

Mobile ad hoc network (MANET) is a self-configuring network. It is wireless as well as infrastructure-less networks. It requires limited energy and resources. In MANET, data travel through the host. Each mediator host acts as a router. Therefore, It is difficult to guess the future location or network topology of the host. Anycast routing is nothing but one to one of many associations. In anycast routing, multiple destinations share the same IP address. From multiple destinations, packet routed to the nearest destination. Anycast is the simplest way of communication. It has minimum communication overhead because packet forwarded to the nearest destination. Therefore, it saves power, network bandwidth and message collision during message transmission. Due to host movement and dynamic changes in network topology stability and QoS of nodes is an important issue in MANET. These issues are addressed by Mobility and QoS aware energy efficient routing protocol. Proposed protocol has three major models: (1) Consistency model to identify stable nodes in network, (2) Traffic model to take QoS into consideration by checking traffic in network and (3) Energy model to make sure the link duration is within an acceptable range. Therefore, high data delivery can be achieved and nodes energy will be taken into the consideration and reduce the link failure due to energy loss. PDR of EMQAR protocol is higher than existing MQAR protocol by 9%. Energy cosumption of EMQAR protocol is less than MQAR protocol by 2%. Dealy of EMQAR protocol is reduced by 1% than MQAR protocol. Control overhead of EMQAR protocol is 10% lesser than MQAR protocol.
