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.

Abstract

The invention provides an energy consciousness and multi-dimensional parameter perception service quality assurance routing method. The method comprises the following steps: firstly, defining two working modes, namely an energy saturation mode and an energy loss mode, establishing an energy cost model, and modifying a data packet format field of a HELLO message, so as to influence flooding frequency, namely HELLO message flooding period time, and achieve the purpose of saving energy; secondly, an MPR node redundancy problem in the network is also subjected to algorithm optimization processing,so that the load of the whole network and the energy use efficiency of the network are improved, and the network performance is further improved; and finally, a routing path selection strategy is improved on the basis of a standard OLSR protocol, and the routing path selection strategy is optimized according to the standard OLSR protocol. Three service quality constraint conditions of link residual bandwidth, link end time delay and node connection time are added, and a single Dijkstra algorithm path selection rule is improved on path selection, so that the reliability of network service quality is comprehensively guaranteed.

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...
