A Wireless Sensor Network (WSN) is ad hoc dense wireless network of small, low-cost sensor nodes (SN), which collect and disseminate sensed data with limited power sources. WSNs can be used in many applications, such as environmental monitoring and object tracking. Organizing network topology with energy efficient traffic can maximize network lifetime. A cellular architecture based on organizing SNs according to their geographical position had been introduced. It uses inheritance features to organize and reduce traffic. It works with ALL-Active (AA) SNs. Moreover, two Energy aware models are suggested to prolong the WSN lifetime. The first uses Cellular Automata (CA) rules and the second uses Radio Triggered (RT) SNs. Multi-hop, Static Tree, Aggregated Tree, Static cluster, and dynamic cluster based routing protocols has been designed and compared for AA, CA, and RT architectures resulting in longest network lifetime with no overhead communication for RT network with least energy consumption applying dynamic cluster routing.
