In our experiments, 42 MICAz nodes were used. The experimentswere conductedwith multiple randomly generated layouts under two different scenarios: (i) an open parking lot, and (ii) an indoor office. In each sce- nario, two types of experiments were conducted: Fixed Single Sender and Round Robin Sender. In the Fixed Single Sender experiment, the sender was placed in the center of the topology, while the other 41 nodes were randomly deployed as receivers. The sender broadcasted a packet in every 200ms. Each packet was identified by a sequence number. The total number of packets broad- casted was 6000. In the Round Robin Sender experi- ment, each node in turn broadcasted 200 packets with time.
