摘要：Ad hoc wireless networks can be deployed quickly anywhere and anytime as they eliminate thecomplexity of infrastructure setup. The main reason for degradation in mobile ad-hoc network performance as a resultof node mobility due to the traffic control overhead required for maintaining routes in the case of table-driven protocoland maintaining routes in the case of on-demand protocol. Mainly the performance goes down when we considered themobility for the network. The effect of mobility on fundamental communication and network performances metricessuch as the bit error rate (BER) of multi-hop route joining a source-destination pair, and minimum required node spatialdensity of an ad-hoc wireless network for full connectivity. This paper discuss the impact of mobility and enlightenedthe importance in real scenarios for pedestrian and vehicular speed using two distance vector routing protocols namely:destination sequenced distance vector (DSDV) and dynamic source routing (DSR) protocol. Here source nodemovement, destination node movement and all node movement have been considered using different mobility periodand also try to judge the QoS parameter for such scenario. BER of an average multi-hop route directly affects theability of an ad-hoc network to support applications requiring a specific BER, for a given node transmission power andnode spatial density.
