In this paper, we propose to design an adaptive energy efficient forwarding data aggregation technique for wireless sensor networks. Initially we form clusters and a coordinator node (CN) is selected near the cluster in order to monitor the nodes in the cluster. The CN selects a cluster head (CH) in each cluster based upon the energy level and the distance(More)
— Cognitive Radio is the wireless technology which allows the effective spectrum utilization among unlicensed users. Basically spectrum resource management is a tough task in present world because of the allocated spectrum to a primary user gets unutilized. In order to avoid the spectrum band unutilization among the users we use cognitive radio technology.(More)
Signal detection is a fundamental problem in Cognitive radio. In this paper a new statistical test is proposed based on random data matrix (RDM) for detecting the signals in noise, as opposed to the eigenvalue based tests. Among the many spectrum sensing methods, the RDM method detects the primary users without any prior information. The performance of the(More)
Extensive research has been done on reliable data forwarding in sensor networks. Existing protocols provide reliability at the cost of high energy consumption. In Wireless Sensor Networks (WSN), data aggregation is essentially used to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. Power consumption is an(More)
