The nodes being used in Wireless Sensor Networks (WSN) pose particular challenge to communicate with one\r\nanother using TCP/IP especially when considering security applications. This paper investigates the limitations of\r\ncurrent TCP/IP structure and an integration using micro IP (�µIP) and proposes an enhanced security technique for\r\nWSN nodes to solve issues arising from the node congestion due to data distribution of keys with a better method\r\nfor securing the data in the network. The summation of this method involves the integration of �µIP stack to key\r\nmanagement scheme, allowing the network to have extra security in the transmission and reception of data, and can\r\nbe applied in hazardous areas where the sensor nodes are used without complications.
