Show full item record Abstract A collection of mobile nodes can form a multi-hop radio network with a dynamic topology and without the need for any infrastructure such as base stations or wired network. Each mobile node acts as both a router for other nodes traffic, as well as a source of traffic of its own In this thesis we develop and present a new hybrid routing protocol called Multipath Distance Vector Zone Routing Protocol, which is referred to as MDVZRP. In MDVZRP we assume that all the routes in the routing table are active and usable at any time, unless the node received or discovered a broken link. There is no need to periodically update the routing tables, therefore reducing the periodic update messages and hence reducing the control traffic in the entire network.
However, the dynamic topology and spatial heterogeneity that characterize VANETs make this challenging, requiring a fundamental change from traditional topology-based routing protocols. In this thesis we focus on the development of specialized vehicular geographic multi-hop communication protocols that address these challenges.
Instead of choosing a single relay as is traditional, DAZL specifies a geographic forwarding zone and has multiple vehicles inside it cooperate in forwarding. Moreover, zone nodes coordinate to prioritize the best forwarders and avoid replication. LASP addresses the issue of spatial heterogeneity by using measured spatial connectivity information describing the probability of delivery between different geographic areas.
Observed vehicular connectivity data exhibited a strong correlation between location and packet delivery ratio, justifying the use of spatial connectivity as an heuristic. LASP combines global historical spatial connectivity information with real-time local neighborhood information to select a next hop that maximizes end-to-end delivery probability.
Throughout the thesis we leverage two vehicular testbeds currently deployed in the city of Porto, Portugal, to both validate the concepts underlying our protocols and evaluate their performance.Many applications as well as various unicast routing protocols such as Dynamic Source Routing (DSR), Ad Hoc On Demand Distance Vector (AODV), Zone Routing Protocol (ZRP), and Location Aided Routing (LAR) use broadcasting or a derivation of it.
