Improved Chain Based Routing Protocol for WSN

Abstact: A WSN is a specialized wireless network made up of a large number of sensors and at least one base station. Recent technological advances in communications and computation have enabled the development of low-cost, low-power,small in size, and multifunctional sensor nodes in a Wireless Sensor Network (WSN). Since the radio transmission and reception consumes a lot of energy, one of the important issues in wireless sensor network is the inherent limited battery power within network sensor nodes. In order to maximize the lifetime of sensor nodes, it is preferable to distribute the energy dissipated throughout the wireless sensor network .Routing protocols are designed to use energy of the sensor nodes efficiently. In our proposed work we are changing the idea related to the data gathering and transmission protocol Chiron. The main goal of our research is reduce of energy consumption and improve the lifetime of network as chain leader belonging to the certain covering angle will only transmits the gathered data to the another chain leader of the same covering angle and then we send the data of the another covering angle in sequential manner. By this method we found that energy consmption is reduced and lifetime is improved significantly. We take the 100m*100 m area and 100 nodes for 3000 iterations for simulation.
