Abstract: Routing is the major challenge for sensor networks. It presents the trade- off between efficiency as well as responsiveness. There are various protocols existing in this category. In this work, we analyse 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 this proposed work is ABC (Artificial Bee Colony) optimization method. Utilization of PEGASS is done because PEGASIS is a redirecting method, so 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. Performance of whole simulation is being done using various metrics like Number of alive nodes, Data Packets received at base station and Energy consumption.
