Research On Routing Protocol For Multihop Cellular Network Based On Ad Hoc

Along with the arrival and developments of information ages, the mobile communication has become an important factor of the society progress and economic development. Currently, there were already extensively existed cellular network of the fixed base station. The traditional cellular network has a certainly limitation. Encouraged by the increasing popularity of Ad hoc networks, there has been interest in incorporating their multi-hop nature into cellular networks. Multihop cellular networks require less transmit power than single hop cellular networks, which increases battery life. Moreover, the coverage is improved by allowing a mobile in a propagation dead spot to be relayed by its neighbors. Thirdly, less total transmission power leads to less interference, potentially increasing the capacity.In our work, we integrated the Ad hoc networks into the cellular networks. Then, we introduced some multihop cellular network models and some basic routing algorithm. At the same time ,we putted forward one new kind of routing algorithm ---- According to the complex minimum power of the stable routing algorithm, that some nodes which are in the outside of the coverage area of base stations are able to connect to base-station by using an according to the complex minimum power of the stable route.Chapter 1 introduced the evolution of wireless communication technology, the evolution of Ad hoc networks,and the main contents of my thesis.In Chapter 2 we detail described on cellular wireless communication system. Here, we introduced the basic concept of cellular wireless communication system and system capacity. Some techniques which aim to increase the system capacity and some arithmetic on power controlling were also introduced in chapter 2.Chapter 3 mainly focused on Ad hoc networks. We introduced two aspects here: the characteristic of Ad hoc networks, and the routing algorithm of Ad hoc networks.Chapter 4 presented the complex minimum power of the stable routing algorithm in detail. Firstly, the multihop cellular network system model was described. Then, the creation and maintenance of the minimum power of the stable routing algorithm were introduced.Chapter 5 was the last one. Here, combined with multihop cellular network system model, we were carry on simulating with the complex minimum power of stable routing algorithm. We then presented the results of simulation.
