Wireless communication consumes a significant amount of energy in wireless networks. Most multi-hop wireless routing protocols are adopted from wired network routing protocols and use pre-selected single or multiple minimum cost paths to forward data packets. However unlike wired networks, a wireless network has unique characteristics such as unreliable wireless links and multiple receivers ass...

The cell size in mobile networks is decreasing to accommodate more users in the same bandwidth. Smaller cell sizes increase the number of handoffs between cells and the probability of encountering a cell with more users than the bandwidth can accommodate. Packet techniques can reduce the work that is performed in a handoff and reduce the probability of losing a connection in an over populated c...

TCP congestion control works well in wired Internet network but it is difficult to determine a good congestion window in a heterogeneous wireless network that consists of the wired Internet and various types of wireless networks. Therefore, we propose herein a novel adaptive window congestion control, namely TCP-Taichung, for TCP connections in heterogeneous wireless networks. The proposed RTT-...

The common trend in the new century has been for wireless computer networks to replace wired ones, due to increased mobility and greater convenience. Since the wireless network is simply broadcasting a signal, which anyone can connect to this Wireless Local Area Network (WLAN) and receive the signal with the proper equipment. Thus, these types of networks are fundamentally less secure than the ...
