为了增强无线传感器网络的动态适应性和实现数据包的最优传输，根据CTP算法的原理，使用NesC语言在TinyOS 2．x下设计改进路由协议ICTP。该协议采用传输期望值指引路由包和数据包进行传输，并在数据包传输过程中考虑下一跳邻居节点的剩余能量以实现动态均衡网络能耗。通过TOSSIM仿真实验表明，改进后的ICTP能够有效减少传输时延，延长网络寿命，提高网络能量均衡。

To enhance the dynamic adaptability of wireless sensor networks and achieve optimal packet transmission,this pa-per designed a collection tree protocol algorithm based routing protocol by NesC programming language based on TinyOS 2.x operating system called ICTP.The protocol used transmitted expectations to guide routing packets and transmit data packet, and considered the residual energy of in the next-hop neighbor nodes in order to achieve dynamic equilibrium of network energy consumption in data packet transmission process.TOSSIM simulation results show that the improved ICTP routing protocol can effectively reduce the transmission delay,prolong network lifetime and improve network efficiency.
