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.
