Abstract.
Wireless sensor networks consist of several tiny sensor nodes largely
which were largely deployed to monitor the environment conditions. Each
sensor node will forward the data wirelessly to the base station using IEEE
802.1.5.4 standard. The wireless network management will be different
depending on the applications. In wireless sensor networks routing protocols,
there are many control messages. Because of the limited resources in wireless
sensor networks, routing protocol has to design to consider the energy. This
paper proposes the new method based on AODV routing protocol to find the
route using cross layer design. The proposed routing protocol can save the
energy and reduce overhead compared to the original AODV.

Introduction
Wireless sensor networks (WSNs) have witnessed a growing interest in deploying.
Sensors are expected to be low cost and can be applied to many applications. In the
network having many sensors using multi-hop communication is required the routing
protocol for to find the communication path and maintenance the route [1]. There are
many routing protocols in propose for WSNs depending on their applications. In this
research focus on multi-hop communication, therefore choose AODV routing
protocol. But AODV designed for mobile ad-hoc network (MANETs). This protocol
is not appropriate for WSNs because of there are still many limits of energy and
resource [2]. Sensor node to send - receives packet low remaining energy than other
sensor node. AODV protocol use route discovery to find a new path. But in route
discovery is not energy parameter. If AODV choose low energy path. When some
node in path is power off. AODV broadcast message control to find a new route. It
effect to high routing overhead, waste energy and bandwidth.
This paper proposes the new algorithm to improve AODV for WSNs applications.
Modified AODV the route discovery called Energy Weight -AODV (EW-AODV)
