In mobile Ad Hoc networks, geographical routing protocol was a kind of important routing protocols, which requires the underlying topology be planar, sparse, connected and t-spanner in order to guarantee the delivery of message and bound the routing length. A new topology control algorithm named ODT, which constructed the geometry structure named ODT graph, was proposed.

基于移动Ad Hoc网络的特性，提出了一种适用于移动Ad Hoc网络的路由协议PAGPSR(Power-Aware Greedy Perimeter Stateless Routing)，该协议在原有的基于地理位置的路由协议GPSR的基础上增加了节点能量感知和负载均衡算法，修改了GPSR的转发策略，使网络中能量消耗和网络负荷分布更加均匀，从而延长了整个网络的生存时间。
