Mobile Awareness Routing Protocol for Mobile Wireless Sensor Networks Based on Optimal Relay Nodes

Mobile sink is a kind of node with mobility in wireless sensor networks, which is proved to balance the energy consumption of the whole network effectively and solve the "Energy hole" problem. The central focus of the study is to build a dynamic route from the sensor to the mobile sink. A mobile awareness routing protocol for mobile wireless sensor networks based on optimal relay nodes (MAOR) is proposed. First, the network is divided into clusters according to LEACH. Then the nodes percept the movement of the mobile sink and found the relay nodes on the optimal forward position calculated by the relevance of communication distance and energy consumption. Finally, the data collected by the clusters is transmit for the sensor to the mobile sink through the optimal relay nodes. Experiment result show that the MAOR is of benefit to achieve an evident improvement of network lifetime.
