Increasing utilization of wireless sensor networks Leads scarcity problems in spectrum allocation channels. The development of cognitive radio networks over wireless spectrum technology based on both licensed and unlicensed user. The maximum interference of users are mitigated to use unlicensed bandwidth. Due the high interference of bandwidth sharing enormously by secondary users (SUs). To sense the unlicensed user on over problematic condition remains the overhead problems on cognitive radio networks. In this paper, Co-operative spectrum sensing as well as spectrum allocation with Forager Bee’s Intelligence algorithm is used. The idle spectrum band in licensed band is identified and allocated to sensor nodes, which reduces the interference and collisions in WSN and avoids packet retransmission. This ensures fair energy in WSNs and Spectrum resources are utilized efficiently.

无线传感器网络利用率的提高导致频谱分配通道出现稀缺性问题。基于许可和非许可用户的无线频谱技术上的认知无线电网络的发展。减少了用户的最大干扰，以使用未许可的带宽。由于二级用户（SU）带宽共享的巨大干扰。在有问题的情况下感测未经许可的用户仍然是认知无线电网络上的开销问题。在本文中，使用了合作频谱感知以及使用Forager Bee的Intelligence算法进行频谱分配。识别许可频带中的空闲频谱频带并将其分配给传感器节点，这可以减少WSN中的干扰和冲突，并避免数据包重传。
