Research on Communication Technology and Routing Algorithm of Wireless Heterogeneous Network

The goal of future communication technology is that anyone can communicate with anyone else in any way at any place and at any time. The existing network or because the coverage is not wide enough, or the bandwidth provided is not high, so that a single network can not meet the future communication needs. The mutual integration between heterogeneous networks with different coverage and service provision capabilities has become the inevitable trend of network development. With the acceleration of the pace of life, the standby state of communication terminal has a greater and greater impact on the selection of network. Therefore, a communication technology and routing algorithm based on wireless heterogeneous network are proposed. The algorithm defines three terminal standby modes, defines the network gravity judgment formula used to measure the network performance, and puts forward different network switching trigger strategies according to different standby modes, And it can prolong the standby time of the terminal, so as to ensure the user's communication experience.
