However, these routing mechanisms increase the communication load of wireless sensor networks, resulting in energy loss

In the architecture of the IPv6 router protocol stack, the routing protocol needs to be supported by IPv6, so as to realize route notification and data packet forwarding, but the routing establishment process of the sensor network is realized inside the sensor network, and the interconnection with the Internet is completed by the sensor network convergence point , so the packet format of the routing protocol implemented by IPv6 is complex, which increases the number of bits received and sent by sensor nodes, resulting in energy loss

The message format of the AODV routing protocol is complex. According to the energy consumption of sensor nodes, the energy required to transmit 1-bit information at a distance of 100m is approximately equivalent to the energy consumed by executing 3000 instructions, which is not conducive to reducing the energy consumption of sensor nodes; AODV routing protocol maintenance The process is complicated, which increases the complexity of node processing messages; in addition, the use of Hello messages to judge the reliability of neighbor nodes not only increases energy consumption, but also causes broadcast storms in the sensor network, resulting in data congestion
