Security Protocol for Wi Sense based Wireless Sensor Networks

Aronee Dasgupta, Pritam Gajkumar Shah

Wireless Sensor Networks have emerged as one of the leading technologies. These networks are to monitor crucial environmental parameters of humidity, temperature, wind speed, soil moisture content, UV index, sound, etc. and then transfer the required information to the base station. However, security remains the key challenge of such networks as critical data is being transferred especially when sensor nodes are used in military application in hostile territories. Most sensor nodes currently deployed have constraints on memory and processing power and hence operate without an efficient security protocol. Hereby we propose a protocol which is lightweight and is secure for wireless sensor applications. The protocol is robust and has been tested on a sensor network made up WiSense nodes.
