Link dynamic and mobility measure of a manet with the brownian mobility model
نویسندگان
چکیده
To characterize the behavior of a mobile ad-hoc network (MANET), the Brownian mobility model is studied, where the random coordinators of mobile nodes are modeled by the Brownian motion. Based on the Brownian mobility model, the average relative speed of mobile nodes in a MANET cluster and the expected value as well as the variance of link lifetime are derived for node pairs. The expected link lifetime of node pairs is used to evaluate the average link lifetime of the MANET, and the mobility measure of the MANET is defined with the relative speed. Numerical and simulation results are presented for different cases.

Realistic Mobility for MANET Simulation
In order to conduct meaningful performance analysis of routing algorithms in the context of Mobile Ad Hoc Networks (MANET), it is essential that the underlying mobility model on which the simulation is based reflects realistic mobility behavior. However, current mobility models for MANET simulation are either unrealistic or are tailor-made for particular scenarios. Furthermore, none of the exis...
متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

متن کاملA Simplified Approach to Analyze Routing Protocols in Dynamic MANET Environment
The fundamental characteristic which differentiates MANETs from other wireless or wired network is mobility and node density. Mobile Wireless Ad Hoc Networks (MANET) is a network without infrastructure, where every node functions as transmitter, router and data sink. Therefore, MANET routing protocols are designed to adaptively cater for dynamic changes in topology while maximizing throughput a...

One of the issues discussed in economy is the socioeconomic inequality in the society. Income mobility is another measure which indicates the degree of inequality of opportunity in a society. The extent of income mobility depends on socio-economic status of the individuals. Different socio-economic status leads to further inequality and increases inequality of opportunity. Such inequalities l...
