Wireless sensor network (WSNs) formed from an enormous number of sensor hub with the capacity to detect and process information in the physical world in a convenient way. The sensor nodes contain a battery imperative, which point of confinement the system lifetime. Because of vitality limitations, the arrangement of WSNs will required development methods to keep up the system lifetime. The vitality productive steering is the need of the innovative WSN systems to build the process time of system. The WSN system is for the most part battery worked which should be ration as conceivable as to cause system to continue longer and more. WSN has developed as a significant figuring stage in the ongoing couple of years. WSN comprises of countless sensor points, which are worked by a little battery. The vitality of the battery worked nodes is the defenseless asset of the WSN, which is exhausted at a high rate when data is transmitted, because transmission vitality is subject to the separation of transmission. Sensor nodes can be sent in the cruel condition. When they are conveyed, it ends up difficult to supplant or energize its battery. Therefore, the battery intensity of sensor hub ought to be utilized proficiently. Many steering conventions have been proposed so far to boost the system lifetime and abatement the utilization vitality, the fundamental point of the sensor hubs is information correspondence, implies move of information packs from one hub to other inside the system. This correspondence is finished utilizing grouping and normal vitality of a hub. Each bunch chooses a pioneer called group head. The group heads CHs are chosen based by and large vitality and the likelihood. There are number of bunching conventions utilized for the group Head determination, the principle idea is the existence time of a system which relies on the normal vitality of the hub. In this work we proposed a model, which utilizes the leftover vitality for group head choice and LZW pressure Technique during the transmission of information bundles from CHs to base station. Work enhanced the throughput and life time of system and recoveries the vitality of hub during transmission and moves more information in less vitality utilization. The Proposed convention is called COMPRESSED MODLEACH.
