Over the recent years, one of the most important problems in wireless sensor networks (WSNs) is to develope an energy-efficient and reliable routing protocol and provide network robustness. To achieve these objectives, we propose a new architecture for data dissemination called Two Tier Cluster Based Routing Protocol (TTCRP) for reliable data delivery in WSNs. TTCRP uses resource rich cluster heads...
Wireless sensor and actor network (WSAN) is formed by the collaboration of micro-sensor and actor node. Whenever there is any special event i.e., fire, earth quake, flood or enemy attack in the network, sensor nodes have responsibility to sense it and send information towards an actor. The actor node is responsible to take prompt decision and react accordingly. Sensor nodes have limited resources...
Owing to the growing demand for low-cost 'networkable' sensors in conjunction with recent developments of micro-electro mechanical system (MEMS) and radio frequency (RF) technology, new sensors come with advanced functionalities for processing and communication. Since these nodes are normally very small and powered with irreplaceable batteries, efficient use of energy is paramount and one of the most...
