Performance Evaluation of Multipath Cellular Networks in Obstacle Mobility Model for Downlink Packet Video Communication
Obstacles present in the line of sight transmission path of a wireless signal severely attenuate the received signal power. Extreme fluctuations of the received signal power caused by shadowing can create "Blind spots." Blind spots are areas within the cellular coverage area from where no communication is possible to the Base Station (BS). For single path packet based services link failures results in total loss of communication. The problem of link failure and blind spots can almost be eliminated in the recently proposed Multipath Cellular Architecture (MCA) which provisions up to three different communication links from the Mobile Node (MN) to three adjacent BSs through overlapped coverage.
