Finally, the programme of design for routing protocols is chose in the thesis. Secondly, improved algorithms are introduced in detail. In order to achieve to reduce duplication of data sent in, save energy, prolong the network lifetime and balance the network load, improved algorithms are based on the minimum hops algorithm which is one of the energy-aware routing, When the characters of the minimum hops algorithm are analysed in detail,multi-path routing, adaptive dynamic routing, routing reliability are designed.Then a new algorithm based on minimum hops in plane routing protocol and a new algorithm based on minimum hops in clustering routing protocol are designed in the thesis.

接著详细介绍了本文的改进路由算法，为实现减少数据的重复发送量、节约能量、延长网络寿命、平衡网络负载的目标，本文以能量感知路由之一的最小跳数算法为基础，详细分析了最小跳数算法的特点，设计了多路径修正路由，自适应动态路由，路由可靠性机制三方面的改进方案，并且结合改进方案设计了基于最小跳数的改进平面路由协议和基于最小跳数的改进分簇路由协议，将两种类型算法的优点相结合，提高网络的健壮性与可扩展性。
