The mobile sink can increase the efficiency of wireless sensor networks. It moves in a monitored environment and collects the network nodes information. Thus, by the sink we can balance the power consumption and increases the network lifetime. Determining path of the sink's movement is usually modeled as an optimization problem where finding optimal solutions require collecting value of all the...

The tremendous emergence of different wireless technologies has created many opportunities for extending many Internet applications and services to the wireless domain, and has envisioned many new ones. When we refer to wireless networks, people thoughts go directly to the Wireless Fidelity (WiFi) technology. However, WiFi networks are one type of the wireless networks that have been used for s...

In cellular and wireless local area networks, wireless communication only occurs on the last link between a base station and the wireless end system. In multi-hop wireless networks there are one or more intermediate nodes along the path that receive and forward packets via wireless links. Multi-hop wireless networks have several benefits: Compared to networks with single wireless links, multi-h...

Network security is an important issue especially in wireless networks where the network is open and the network perimeter is not exactly known. This makes them more vulnerable to attacks such as eavesdropping, message interception and modifications. Several security protocols designed for wired-line networks have been adopted for use in wireless networks. However, they may not be suitable for ...

Wireless multi-hop networks have been envisioned to have many potential applications, e.g., a small stand-alone network for a group of mobile users (Mobile Ad Hoc Networks), a costefficient stub-network to connect to the Internet (Wireless Mesh Networks), or a self-organized community network connecting houses together (Wireless Community Networks). However the preliminary deployment experience...
