Abstract

The ad-hoc networks don't necessarily rely on infrastructure such as base stations and the network can be easily constructed autonomously and automatically. However, such network systems use wireless links, therefore the nodes cannot be always surely connected because of the limit of transmission range. Also, the node distribution is uncertain, therefore the connectivity or connectedness for the entire network cannot be guaranteed. In order to guarantee a stable connectivity of networks, in this paper we use the connectivity measure as the degree of connectedness among two or more nodes. By using Shadowing radio model, we calculate the connectivity degree and analyze the performance of ad-hoc network.
