An efficient utilization and allocation of the limited resources of a wireless sensor network (WSN) in a way that maximizes the information value of the data collected is a significant research challenge. Within this context, this result concentrates on architectural approach as a means of focusing a sensor’s on obtaining the important data at heterogeneous environment. Our goal is to facilitate the development of sensor network with to separate all sensors in distributed clusters. Fully collision-free TDMAbased MAC protocol for a WSN cluster was proposed. As we assume that in each cluster every node is one-hop far from its neighbors it’s obvious that no routing protocol is needed and it enables to use very simple sensor nodes with limited resources, which prolongs WSN duty life. Together with upper level content here refers to automatic runtime selection of services implementations and network resources to execute the application specification in a resource-efficient and context-aware case.
