Embodiment Construction

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] refer to figure 1 , the present invention comprises the steps:

[0035] Step 1) Set parameters:

[0036] Suppose there are N numbered nodes S={S on the lunar surface 1 ,S 2 ,...,S n ,...,S N }, each node is both the source node and the destination node of the remaining nodes, where N≥3, S n Represents the nth node, when n=1, S n Represents the communication node of the lander, when n∈[2,N], S n represents the astronaut node carrying the communication machine, then the astronaut node set is S′={S 2 ,...,S n ,...,S N }; Both the lander node and the astronaut node have a communication range with a radius of 5km. Compared with the astronaut node, the lander node has higher initial energy and stronger computing power, but is larger in size, heavier in weight and weaker in mobility. The astronaut node has good mobility and ...

Abstract

The invention proposes a lunar communication system routing method based on the low-power lossy network routing protocol RPL, which is used to solve the problems of high average energy consumption of nodes, unbalanced energy consumption of each node, and routing table information forwarding overhead existing in the prior art. A big technical problem, the implementation steps are: set parameters; each communication node S n Construct own information object message DIO based on RPL message format n ;Each astronaut node selects its own parent node based on the characteristics of the lunar surface autobiographical cycle; constructs a non-storage RPL network topology G 0 ; in G 0 The vital signs data is transmitted between the nodes. The invention can be used in the fields of low-power lossy networks and the like.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and relates to a routing method for a lunar communication system, in particular to a routing method for a lunar communication system based on a low-power lossy network routing protocol RPL, which can be used in the fields of low-power lossy networks and the like . Background technique [0002] Wireless Sensor Networks (WSN) is a multi-hop, centerless, self-organizing wireless network. Low power and Lossy Networks (LLN) belong to WSN, and the nodes forming LLN have the characteristics of limited energy and weak information processing capability. [0003] The lunar surface presents 14 days of polar day and 14 days of polar night, and it will switch periodically. The communication equipment deployed on the lunar surface uses solar energy for energy supply. During the lunar polar night period, there is no energy supply for up to 14 days, so the energy is limited, and the communicat...
