Packet Collisions in wireless communication are one of the most causes of network performance degradation. MACAW mechanism is a popular and widely used mechanism to reduce packet collisions that arise due to the hidden terminal problem in mobile ad-hoc networks. However; Mobility is considered a vital issue in mobile ad-hoc networks that has not been thoroughly investigated. A real time simulation is carried out to measure the Throughput and the Packet Delivery Ratio of an ad-hoc network under Shadowing propagation model using MACAW mechanism with different mobility scenarios.

IEEE802.11 have been fully understood in the networking era. Opnet with IEEE802.11 give assistance is an easily understood able simulation tool for communication researchers. However it's academic Edition have limited abilities. In this paper author have studied performance of IEEE802.11b (WLAN) using various security parameters. Author found that the throughput was decreases with respect increase in number of nodes and packet drop also increases with increase in number of nodes.

As the explosive growth of the ISM band usage continues, there are many scenarios where different systems operate in the same place at the same time. One of growing concerns is the coexistence of heterogeneous wireless network systems. For the successful deployment of mission-critical systems such as wireless sensor networks, it is required to provide a solution for the coexistence. In this paper, we propose a new scheme using inter packet delay for the coexistence of IEEE 802.15.4 LRWPAN and IEEE 802.11b WLAN. To evaluate the effectiveness of the proposed scheme, measurement and simulation study are conducted using Qualnet 4.5 simulation software. The simulation results show that the proposed scheme is effective in performance improvement for coexistence network of IEEE 802.15.4 for various topologies.
