Wireless Sensor Networks consist of sensor nodes and few powerful control mobile laptops performing activities like routing, data aggregation etc over wireless media. These kinds of networks are getting popular these days because of small size, ease of handle and installation. Because of this property they are used in environment like military, hospitals, weather forecasting etc. for processing critical information. However such kind of environment is more prone to “Man In the Middle Attack", where attacker can easily perform malicious activities without interrupting network operation, which can further propagate to other nodes that can alter say routing information and even can degrade the network performance and stability. In this paper we have designed ECC algorithm and implemented it over a simulated network created with the help of Java Sun Spot kit, consisting of two sensor devices and a base station. Here by going through the work done by different researchers where they have compared both RSA and ECC algorithm with the help of automated tool over different factors, it can be concluded that ECC is the most optimal and efficient algorithm for wireless communication. Using Java SunSpot kit a wireless sensor network is formulated and devices are made to communicate with Elliptical Diff-Hellman Algorithm implemented over it, the packet are then captured and verified using the automated tool.
