Abstract

This research discusses questions of routing in wireless mobile networks, not requiring fixed infrastructure and administration. Such networks are called ad hoc networks. The core emphasis of the article is to select the routing protocol, promptly responding to changes in the network, at the same time providing the lowest network load by control traffic at low movement velocity of the nodes. The article discusses various methods for optimization of the algorithm considered. Dynamic Source Routing is a rather simple and effective routing protocol, developed specially for multihop wireless networks of mobile subscriber systems without infrastructure. DSR protocol is designed for use in networks with the number of SsS up to two hundreds and works well even rather high SsS movement velocity.

This research has examined the issues of routing in multi-hop wireless networks of mobile nodes without the need for any existing network infrastructure or administration. This is called ad hoc. The key point of this research article are selecting routing protocols which adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods in which hosts move less frequently. This research article considers different methods of optimization of selected algorithm. The Dynamic Source Routing is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. The DSR protocol is designed mainly for networks of up to about two hundred nodes. It works well with even very high rates of mobility.
