Research On Resource Allocation And Layered Technology In Mobile Ad Hoc

Ad hoc network and communications is a hot research topic in the industry in today, it is also called mobile ad hoc network. Ad hoc networks with anti-risk characteristics and strong anti-destruction makes it has an important prospects. But the network has many problems to be solved. The traditional wired or wireless network, has a relatively complete security solution already currently.These programs can not be directly applied to Ad hoc network because the features of ad hoc networks. In short, ad hocnetwork is flexible and does not depend on the network which has invarible infrastructure, so has great prospect. The flexibility and features of the network brought great challenges to its safety.The main research of this paper focuses the allocation of resources in Ad hoc network, the allocation of resources which connect with the network layer and application layer is the main project of this paper. This thesis work includes the following two aspects:First, my workthe resource allocation scheme in network layer.This document focuses on the impact to the allocation of resources, which bring by the routing protocol. The main content of this chapter is make a introduction of the the traditional routing protocols and give the performance of the network which has used the improved routing protocols. This chapter introduces the traditional on-demand routing protocols, namely AODV, and the DYMO protocol, while these two traditional protocols were compared. The experimental results of the improved AODV protocol and the AODV is simulated by opnet.The results show that compared with the AODV protocol, the improved AODV protocol in packet delivery rate, routing, end to end delay to find the performance of time and have a better performance, which proves that the improved AODV, AODV protocol performance relative to the superiority. Then make a introduction of the improve the DYMO routing protocol. Simulation results show that:the improved DYMO improved packet delivery rate and average in the end to end delay two indicators should be better than DYMO, and with the increase in the number of nodes and node speed increase, DYMO more obvious advantages. DYMO protocol is an improved result for the large-scale wireless network protocol and has good routing performance.Secondly, this paper show the resource allocation scheme in the application layer,the main scheme is about market-based resource allocation, first give the application of the program and the background,the basic market model have been described, then give a description of the network model and the specific distribution plan.At last,the paper give the simulation results of the resource allocation scheme which based on market.Finally, make a conclusion about this research methods,and the future research directions are discussed.
