In addition, the system model of high priority user for the HSSN is constructed and the performance of this network is also evaluated from the angle of discount wedding dresses examining overhead. The HSSN can realize optimization for network architecture and be satisfied with requirement of dynamic spectrum allocation, while it can significantly provide a considerable extension to the available spectrum.Caused by the spectrum heterogeneity in cognitive radio network, it is usually difficult to obtain a common control channel. To solve this problem, the third part of this cheap wedding gown dresses thesis proposes a clustering algorithm based on multiple channel access in the HSSN. Cognitive radio users in the HSSN can share a Local common control channel (the flat iron shop for us) instead of a global control channel in each cluster. Simulation results show that the clustering architecture conducted by the proposed clustering algorithm is stable and efficient in solving the chi flat iron store problem in obtaining a common control channel.The last part of this thesis proposes a decoupled route selection blog lace wedding dresses and spectrum management protocol, which adapts itself well to the multi-hop communication mechanism in the HSSN. This algorithm analyzes the affects from spectrum stability, considers anti-intermittence routing and gives out specific description of computation of route metrics and routing discovery and so on. Besides, a large amount of computerized simulations are shown in this part to evaluate the performance of this algorithm.
