Embodiment Construction

[0065] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0066] Such as figure 2 As shown, a wireless network node cooperative routing method described in an embodiment of the present invention includes:

[0067] Step 1, each node in the initial network broadcasts a neighbor discovery packet;

[0068] Step 2, among the multiple neighbor nodes of the node that broadcasts the neighbor discovery packet, the neighbor node that has received the neighbor discovery packet adds the neighbor information to the neighbor discovery packet, and continues broadcasting;

[0069] Step 3: After broadcasting for a duration of t, the neighbor information around each node has converged, and each node generates a complete neighbor list, and then each node calculates its own neighbor list based on the existing neighbor list information. Rhombus structure;

[0070] Step 4, the routing source node broa...

Abstract

The invention discloses a wireless network node cooperative routing method. The wireless network node cooperative routing method comprises: step 1, a neighboring cell finding packet is broadcasted to each node in an initial network; step 2, each neighboring cell node already receiving the neighboring cell finding packet adds neighboring cell information to the neighboring cell finding packet and continues to broadcast; step 3, after continuously broadcasting for time t, the neighboring cell information around each node has been converged, and meanwhile, each node generates a complete neighboring cell table, and then each node calculates own rhomboid structure according to the existing neighboring cell table information; step 4, a routing source node broadcasting a path-searching packet and carries the rhomboid structure information via a relay node; and step 5, a routing destination node receives the path-searching packet and selects out the optimal path according to the rhomboid structure information. The wireless network node cooperative routing method has the beneficial effects that cooperative communication is realized at the IP layer by use of the rhomboid structure in the wireless adhoc network, and cooperative routing is completed by use of the rhomboid structure, and therefore, the robustness of routing to the mobility of the network is improved and the transmission power of each node is saved.

Description

technical field [0001] The present invention relates to the technical field of wireless networks, in particular to a wireless network node cooperative routing method. Background technique [0002] With the development of smart chips and microprocessors, smart portable devices with perception functions have developed rapidly in the field of the Internet of Things. In such non-infrastructure communication scenarios with random mobility, the communication between devices is the key problem to be solved, and the wireless Ad hoc network is also regarded as a typical network structure of the Internet of Things. Cooperative communication technology can provide cooperative diversity gain, increase transmission reliability, and reduce transmission power consumption. It is one of the communication technologies worthy of attention in wireless communication. [0003] Currently, cooperative communication is mainly applied to the physical layer and the data link layer. At the physical l...
