Abstract: In the beginning the development of wireless sensors was driven by military applications but the introduction of civilian wireless sensor systems has greatly diversified application domain which has further boosted research efforts in the field of wireless sensor networks. The protocols implemented in the sensor network i.e. H-HEED protocol which should be energy aware and simple enough to be implemented in the low-end type of hardware and software of many WSN applications. WSNs H-HEED protocol may be deployed outdoors in large sensor fields to detect the spread of wild fires. The other functionality of H-HEED protocol is: One is the periodic collection of data from other members the cluster and aggregates it. Second, is forwarding the aggregated data toward the base station.
