The movement of nodes challenges the design of routing in Mobile Wireless Sensor Networks (MWSNs). Therefore, Contact time-Energy Consumption Area(CECA) based Routing is proposed in this paper. In CECA routing, all the nodes follow a sleep-wakeup pattern to improve energy efficiency. Communication between the source and the sink is established by creating a rounded rectangle region. Only the nodes in rounded rectangle region participate in the routing. The Contact-Time(CT) between source and neighbor node is computed by mobility information, and the timer is set by CT. The next-hop forwarding node is selected by timer. Simulation results indicate that CECA protocol has better performance in term of packet delivery ratio and connection-time of routing.
