Energy efficiency and network lifetime are key factors in characterizing wireless sensor networks due to the limited energy of nodes. In this paper we present two approaches to routing in wireless sensor networks that utilize the ideas of node cooperation and information exchange to achieve cognition across multiple network layers. In the first proposal, nodes exchange information about their statistical...
The paper presents the criteria that affect the performance of network lifetime in Wireless Sensor Networks. In sensor networks the nodes can be organized into clusters for one hop energy-efficient data routing. This work focuses on adaptive clustering of sensor nodes where the role of cluster head changes among nodes. The nodes take turn to become cluster head based on one or several parameters such...
Putting constraints on performance of a system in the temporal domain, some times turns right into wrong and update into outdate. These are the scenarios where apposite value of time inveterate in the reality. But such timing precision not only requires tightly scheduled performance constraints but also requires optimal design and operation of all system components. Any malfunctioning at any relevant...
