An energy-aware and multi-dimensional parameter-aware routing method for quality of service assurance

Abstract

The invention proposes an energy-aware and multi-dimensional parameter-aware routing method for quality of service guarantee. First define two working modes, energy saturation mode and energy deficit mode, establish an energy cost model, and modify the data packet format field of the HELLO message, so as to affect the flooding frequency, that is, the flooding cycle time of the HELLO message, to achieve energy saving Purpose; Secondly, algorithm optimization is also carried out for the MPR node redundancy problem in the network, so as to improve the overall network load and network energy utilization efficiency, and further improve network performance; finally, in the standard OLSR protocol (optimized link state routing protocol, OLSR protocol) On the basis of the routing path selection strategy, the routing path selection strategy is improved, and the three service quality constraints of link remaining bandwidth, link end delay, and node connection time are added, and the single Dijkstra algorithm is improved in path selection. Path selection rules, so as to comprehensively guarantee the reliability of network service quality.

Description

technical field [0001] The invention belongs to the technical field of mobile ad hoc networks, and in particular relates to an energy-aware and multi-dimensional parameter-aware quality of service guarantee routing method. Background technique [0002] Mobile ad hoc network (MANET) is a wireless network used to connect mobile devices. Devices in the network may move freely in any direction independently, so the connection with other devices will be frequently changed. Continually maintaining the information needed to establish correct routing for each device is a major challenge for MANETs. Compared with some existing networks with a central structure, MANET has lower construction costs and greater space for popularization. [0003] OLSR (Optimized Link State Routing, optimized link state routing protocol) is a routing protocol mainly used in MANET networks. It optimizes the classic link state algorithm to meet the requirements of MANET. The key to optimizing the link sta...

Problems solved by technology

When the standard OLSR protocol calculates the route, it only selects the route through the number of path hops, but in the actual environment, there are other influencing factors, such as fixed node energy and network service quality.
