Abstract: Routing is the major challenge for sensor networks. It presents the trade- off between efficiency as well as responsiveness. There are various protocols exist in this category. In this work, we have analysed Power Efficient Gathering in Sensor Information System (PEGASIS) hierarchical protocol for routing with the protocols on the basis of total energy consumed, sensors lifetime and provides a comparison with traditional methods. The optimization method used in the proposed work is ABC (Artificial Bee Colony). Utilization of PEGASS is done as it is considered as a redirecting method and allows good routing. This method employs some sort of greedy approach beginning from the actual furthermost node and each of the sensor nodes form some sort of string just like composition. The proposed work has been designed and implemented in WSN by using PEGASIS routing protocol. In this work, the performance analysis of the network with the scenarios consisting 50 nodes moving with the speed of the 5-10m/s within the area (1000X1000) m2 has been done in regards to the parameters packet delivery ratio, Throughput, End-to-End Delay, and Energy consumption.
