Improve the Energy Efficiency in Cognitive Radio Sensor Network using Spectrum Allocation

Cooperative routing and range spectrum aggregation are two promising methods for channel sensing and switching. In this paper, we propose a Cognitive Radio Sensor Network (CRSNs) based cooperative routing protocol, termed as licensed channel, termed as cluster, for intra-cluster and inter- cluster. To the best of our insight, this is the first commitment on range accumulation based agreeable directing for CRSNs. The essential target of channel data transmission is to give higher vitality productivity, enhance throughput, and reduces system delay for Time Division Multiple Access (TDMA). A Cognitive Radio (CR) network (i.e., secondary network) opportunistically shares the radio resources with a network (i.e., Primary network). A CR-based cellular network where a cluster network shares a spectrum that belongs to an indoor system. Reducing the end-to-end delay channel is reduced. The analysis will highlight the impact of the multi-user diversity gain of both the primary and secondary users on the achievable spectral efficiency. The constraints on the reliability of sensing, the throughput and the delay of secondary User (SU) transmission. The optimal value of sensing time depends on SU waiting current channel. Found out to make the energy consumption of one data packet transmission minimized.
