Abstract: As the World Wide Web becomes increasing popular, internet traffic also increases, thus increasing user perceived latency (UPL). Web page prefetching is seen as a potential solution. It involves trying to predict the user's next request and acquiring that web page while the user is busy reading their current web page. Prefetching has been an area of research interest in wired systems. Such research has shown that prefetching does lead to a reduction in UPL. However prefetching research for wireless mesh networks, where unlike wired systems, data traffic traverses through multiple mesh routers, which are susceptible to failure, and which can be used by numerous mesh clients to access a gateway access point is nil. This thesis applies the principles of prefetching to wireless mesh networks. Test results show for mesh clients, UPL is indeed decreased. Moreover this decrease in user perceived latency is also accompanied with the interesting result that there is a transformation in the distribution shape of UPLs as one goes from a wireless mesh network system that does not engage in prefetching to one that does use prefetching.
