Abstract:
IEEE802.16 protocol is being developed and 802.16 modems will be used in every house to connect to the Internet through base-stations in both urban and rural areas. Since user bandwidth for connection to the Internet is limited, a large fraction of each modem’s bandwidth is not used. In this thesis, we propose an architecture to make a PPMN (Public Peer-to-peer Mesh Network) of all users in a city. Users can be wired or wireless under any authority. They have to forward intra-city traffic themselves. As a result, it is not required to transfer intra-city traffic through BSs except for critical information. The architecture is composed of a routing algorithm, a forwarding incentive mechanism, and a security-resiliency scheme. Design challenges are discussed in each case. Two resiliency schemes, 1) multipath routing and 2) OHOF, are proposed which should be used together to provide an acceptable level of reliability in PPMN. We show that our routing algorithm is scalable and resilient against routing misbehaviors. We have simulated routing overhead and resiliency against packet loss
