The growing popularity of sensor networks has resulted in the creation of various MAC protocols, each optimized for a different set of application requirements. However, all of these heterogeneous MAC protocols are designed under the assumption that all nodes in the wireless environment use a common MAC protocol. When multiple sensor networks are deployed in the same wireless environment, this assumption no longer holds since different sensor networks will most likely make use of different MAC protocols. This paper investigates the effect of interference between sensor networks using heterogeneous MAC protocols, based on the network performance of these sensor networks. The network performance of TDMA, CSMA/CA, T-MAC and LPL-MAC, a variant of B-MAC, is examined.
