Hopping Strategies for Adaptive FH-CDMA Ad Hoc Networks Under External Interference

Free registration required

Executive Summary

The authors discuss the performance of an adaptive FHCDMA ad hoc network under the influence of external interference where node positions are modeled by a homogeneous Poisson point process. The optimum channel assignment that balances internal network interference due to spatial reuse and external interference is derived analytically for a path loss and Rayleigh fading model. The performances of the resulting hopping strategies are then compared to various suboptimal hopping strategies such as non-adaptive hopping and min-max allocation with constant QoS.
