Study on Indoor and Outdoor Environment for Mobile Ad Hoc Network Supported with Base Stations

Most of MANET simulations based on random mobility models, e.g. random waypoint model, models insufficient to reflect the environmental constraints. In this paper, we evaluate an ad-hoc wireless network and investigate on performance issues in urban area. We have tried to simulate by adding base stations to adhoc architecture in urban area for wireless networks and compare their performance based on a number of factors. In this study we have used two type of mobility model (Manhattan mobility model and random waypoint mobility model). We have used ns-2 for all our simulations. In all our simulations, we have tried to quantify the effects of factors like routing protocols, mobility patterns and type of traffic, that affect the performance of ad hoc networks. Specifically, this paper evaluates the impact of these factors on the following performance metrics: throughput, packet delivery ratio and dropped packet.
