We studied the performance of MultiNet using a real implementation and a custom simulator. The implementation was used to study the throughput behavior with different switching algorithms. We then simulated MultiNet and compared it with the alternative approach of using multiple radios to connect to multiple networks. We compare the two approaches with respect to energy consumption and the average delay encountered by the packets. The results presented in this section confirm that MultiNet is a more efficient way of achieving connectivity to multiple networks as compared to using multiple radios.
