Abstract:
A Wireless Sensor Network is a group of small sensor nodes which are used to cooperatively monitor physical or environmental conditions. Each node collects events or data from the field of interest, which seems inaccessible at the most time. By using the wireless communication capacities, sensor node sends its information to the remote base station where the end-user can access data. To deal with this, an appropriate energy-efficient routing algorithm is needed to the inherent characteristics of this kind of networks. The objective of our paper is to extend the whole network lifetime by applying two routing algorithms, one on the entire network and the other, on a special area called a hotspot, with the aim to tackle the problem of the isolation of the sink node caused by the depletion of the energy of sensor nodes surrounding it. The first protocol is based on residual energy and link distances, and aims seeking the optimal path from the sensor node transmitter to the sink node. The second protocol is based on the equitably distribution of the energy over all nodes located in the hotspot area and avoids the isolation the sink node from the rest of the network.
