For mobile sensor networks, it is important for nodes to exchange data so that the data delivery probability can be increased. In order to communicate with each other, nodes need to detect each other through sending and receiving beacons. Due to the strict constraint of energy supply, a sensor node without being in sleep mode cannot work long enough to meet the applications' lifetime requirements...
Due to the traversal-multicast data transmission manner of the sensor network, the energy consumption of the network is unbalanced and the nodes close to the sink will consume more energy and die faster. This leads to the energy hole problem. In order to solve this problem, many non-uniform node deployment schemes have been proposed for event detection sensor networks. All these works did not consider...
In order to tackle the energy hole problem of sensor networks, the non-uniform node deployment strategy was presented recently. For achieving the expected performance of this deployment method, nodes need to transmit data to the sink node through selecting a node in the adjacent inner-region decided by the deployment strategy. Since nodes near the outer-boundary of a region will be covered by more...
