Clustering data dissemination in wireless sensors network

Data dissemination in wireless sensor networks is very interested issue. In this area many researches have been published, most of them consider the problem of the power management and try to implement an efficient energy in their protocols. Moreover, the special characteristics of sensor nodes like limited battery power, limited computing capability and low bandwidth make the data dissemination protocol design very complex. Therefore, in our data dissemination design given in this paper, we propose new power management scheme using dynamic power threshold. The proposed protocol starts by an initialization phase, in which the sensor network will be organized under grid virtual and in each cell a cluster head will be selected. In the second phase, the data dissemination process begins to disseminate the detected data from sensor node to the sink. The simulation result shows that the proposal protocol consumes less energy and has a longer network lifetime compared with other previous protocol.
