I}mproved Chain based Hierarchical Data Gathering Protocol for {WSN

Ravinder Kumar

In this paper, Wireless sensor network [1] nodes which are very tiny in size and their cost is also not very high. They are deployed in any geographical region in a random fashion. During the process of data sensing, data gathering and data transmission, the charge of the power unit associated with any node gets low, after certain time i.e., each node has its life time. The life time of nodes directly affects the life time of the sensor network. As each node is very low in cost, it is unnecessary and difficult too, to recharge them once their energies are exhausted. Therefore, it is very important to conserve the power of the nodes so that the life time of the entire network can be conserved. Hence the requirement of a power efficient data gathering protocol is very important to serve the purpose in wireless sensor network. In the proposed work, it is being tried to change the idea relating to the data gathering and transmission of the existing mode i.e. Chiron as, chain leaders belonging to certain covering angle will only transmit the gathered data to the another chain leader of the same covering angle in sequential manner. In this way our research can provide better efficiency, resource consumption and lifetime.
