Low power sensors are emerging to up held the current edge technology. Sensor devices linked to each other via short ranged radios form wireless sensor networks (WSN). In recent development, WSNs are utilized for Internet of Things (IoT) applications like monitoring, automation and control, etc. The data collected is dumped on internet cloud so that easy access to data from remote place is possible. The most crucial feature of sensor device is energy saving as these are battery driven circuits. This work proposes the extension version of a distributed cluster computing technique to save battery energy and extend the WSN lifetime. The modified protocol inculcate cluster formation based on event occurrence, which gives improved results in terms of network lifetime compared to its conventional protocol. Simulation results also shows that proposed protocol is scalable thus can be used for IoT systems. © 2017 IEEE.
