Advancements in technologies, semiconductor industry and communications resulted in construction of wireless sensors. Wireless sensors are self-managing and sensing devices having the capability to communicate with each other and sink node wirelessly. The sink node can then take decision according to the application they are being used for; upon the reception of messages from node. Generally, transport control protocols provides reliable data transfer with congestion control and recovery support. This support is very important in wireless networks where data is more likely to be lost than wired network. In Wireless Sensor Networks (WSN), there are limited resources like energy, memory, and signal strength.
