Abstract:
The implementation of multi-channels at the MAC layer has created a new interference problem, the Missing Receiver Problem (MRP). The MRP is a multi-channel problem which relates to the use of multi-channels concurrently. As nodes communicate on different channels, they become unreachable and deaf. Bandwidth will be wasted when communication is initiated with deaf nodes. The paper evaluates the effects of MRP on network performance. The bandwidth of one control and two data channels is considered in relation to the size of control and data packets. Channel switching delay is also factored in the analysis. An analysis of channel bandwidth given the size of packets is presented. The proposed MRP solution is based on the cyclical scheduling algorithm, a proposed framework for solving multi-channel interference challenges. The framework is described at length and thereafter the analyses and the analytical results are discussed. The results show that the effects of the MRP can be reduced.
