Abstract

Energy conservation is the critical design issue in wireless sensor network(WSN),since sensor nodes are energy constrained. Each sensor nodes relies on its limited battery power for data acquisition, processing, transmission and reception. Sensor nodes uses low power multihop wireless transmission mode to route the data messages from source to base station. Since most of the energy of a sensor node is spent in data transmission, routing of data messages is particularly a major issue. Several routing schemes have been proposed to utilize the available limited energy resource of sensor nodes efficiently with the objective of prolonging the lifetime of sensor networks. Besides maximizing the lifetime of sensor network, it is preferable to distribute the energy dissipation among the nodes to avoid early depletion of the network. In this paper, an attempt is made for distribution of load across nodes uniformly by considering energy and past communication activities at each node. To address this issue, our algorithm constitutes a new path for each iteration by selecting suitable nodes having energy not less than energy required to forward the sensed data messages. Here there is no dependency on specific nodes to forward the data messages, this feature makes algorithm adaptive. Eventually, the proposed scheme provides a good chance to all nodes to actively participate in forwarding data messages and thus helps in achieving our goal to distribute the load. A value, called threshold, which varies with size of the sensed data message, despite preventing the early death of heavily involved nodes due to battery drain off, force the nodes to enter into reduced activity, thus enhancing the network lifetime.
