An Implementation in AODV based on Active Route Timeout between sensor nodes in Wireless Sensor Networks

Abstract— Wireless Sensor Network is a technological development of small, low cost, low power devices that combine data processing with multiple sensing and the ability to communicate wirelessly. Routing in sensor network is a point of concern for researchers. Many researchers has been proposed various routing algorithm for conserving network resources specially energy consumption due to transmission of sense data in the network. AODV is a reactive source-initiated routing protocol which is sensitive to several parameters such as ACTIVE_ROUTE_TIMEOUT, NET_DIAMETER MY_ROUTE_TIMEOUT, and RREQ_RETRIES, HELLO_INTERVAL. In this paper we proposed a dynamic version of AODV i.e. ARTO-AODV in which active route timeout varies from one second to many seconds. ARTO-AODV can be used in large , middle and small networks depending upon the type of application such as battlefield monitoring system, hospital monitoring, wireless remote meter-reading system and so on. Simulation shows that ARTO-AODV clearly outperforms with respect to packet delivery ratio, throughput, average end to end delay, and energy efficiency.
