Abstract−Wireless sensor network (WSN) is built of different sensor nodes. These nodes may be of different types for different kind of application. There quantity also varies from few nodes to hundreds or thousands depends on particular application. The most important resource on these nodes is the energy supply and in almost all the cases a battery in the node is responsible for supplying energy for the entire lifetime of the node. The deployment of nodes could be at inaccessible locations and hence once the battery has drained the node is unusable for the network. Therefore it is very essential to conserve energy as much as possible. One possible solution to conserve this energy is to use efficient data coding techniques in sensor nodes. As we know while transmitting of data transmission of 1’s consumes much power than transmission of 0’s in wireless medium, so it is very beneficial to use silent zero communication coding technique for transmitting data in order to reduced total energy consumption of a sensor node. Here we are going to present some silent zero communication techniques which have been specially designed for wireless sensor networks. Such as:
