The wireless sensor networks have been experiencing exponential growth in the past decade. A wireless sensor network (WSN) provides low cost solutions and consists of several sensors distributed across a geographical area. In many commercial and industrial applications, it often needs to monitor and collect the information about the environment conditions (temperature, humidity, vibration, acceleration etc.) by using sensor networks. Recharging or replacing sensors batteries in a large geographical environment is not a feasible task. In this paper we have identified important issues pertaining to energy consumption of wireless sensor network (WSN). Also, we aim to resolve issues relating to excessive multi-hoping from one node to another and propose an addressing scheme refer to a node that can also be used for signal spreading and de-spreading and a protocol to minimize power usage. The proposed Improved Energy Efficient Communication Protocol (IEECP), comprises of moveable sinks and sensors node that can be randomly deployed in the network. Proposed protocol is compared with the two existing protocols namely Tree Routing (TR) and Enhanced Tree Routing (ETR). The simulation results show that the proposed protocol has the lowest hop-count compare to TR and ETR. And reduces hop-count, excessive multi-hoping and prevents flooding of path search messages in a dense sensor network, and thus saves energy of the sensor nodes.
