Abstract
Ad hoc wireless networks have gained worldwide attention from both academic groups and individual consumers in recent years. There are many very tiny autonomous networking, connectivity, and sensing systems with minimal energy and computational resources that function together to accomplish a big sensing mission. Wireless sensor systems include multiple sensing devices, some computing technology, and limited power supplies connectivity and processing capabilities that jointly serve a major sensing mission. Wireless sensor networks focused on IEEE802.11b pose a few concerns such as battery scavenging for a limited power source. Therefore, the proper functioning of such a device relies on wireless motes `resources. In this paper, two theoretical models showing and forecasting the QoS as regards performance. The performance of star topology is 15 percent better than the grid topology in throughput. while the average end-to-end delay record is 17.25 ms and 76.25 ms respectively for star network topology and grid networks topology. The jitter decreases with a growing data rate of (1 to 11) Mbps in grid and star topology, the average jitter in star topology less than in grid in all tests. in terms of energy, in a star network, the average energy usage was 0.065 mWh while the average in grid record 0.045 mWh. These two distinct IEEE 802.11b network architectures are cluster-based and grid-based and are validated using simulators Qual-Net.
