Over the last years research on wireless multi-hop networks has gained momentum. Wireless multi-hop networks come in many different flavors, all having their own characteristics, requirements and specific constraints. While ambiguous definitions of multi-hop networks are used in the literature, we believe that different types of multi-hop networks should be differentiated more clearly. With thi...

MIMO-based communications have great potential to improve network capacity for wireless ad hoc networks. Although there has been significant progress on MIMO at the physical layer or single-hop communication over the years, advances in the theory of MIMO for multi-hop ad hoc networks remain limited. This stagnation is mainly due to the lack of an accurate and more important, analytically tracta...

Ad Hoc Networks are characterized by multi hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. In this project, we make a performance analysis of two of the protocols proposed for ad hoc networks using the extended ns-2 simulator Keywords— Ad Hoc Networks, Routing protocols, Global State Routing, Dynamic Source Routing

IEEE 802.11 MAC is the most commonly used protocol in multi-hop ad-hoc networks which need no infrastructure. In multi-hop ad-hoc networks based on IEEE 802.11, since nodes try transmitting their packets at every possible slot, there is a high packet loss probability. This degrades network performance attributes such as throughput and fairness. In this paper, we focus on achieving the maximum t...

Handoff performance is a critical issue for mobile users in wireless cellular networks, such as GSM networks, 3G networks, and next generation networks (NGNs). When ad hoc mode is introduced to cellular networks, multi-hop handoffs become inevitable, which brings in new challenging issues to network designers, such as how to reduce the call dropping rate, how to simplify the multi-hop handoff p...

In the last decade a new paradigm in computer networks gained a lot of popularity, especially in the wireless network research community: mobile ad hoc networks. The main difference between this new and the existing conventional networking paradigm lies in the architecture of the network and the role of the different network components. In the conventional paradigm, a person with a computer con...

Many previous papers have pointed out that TCP performance in multi-hop ad hoc networks is not optimal. This is due to several TCP design principles that reflect the characteristics of wired networks dominant at the time when TCP was designed, that are not adequate for multi-hop ad hoc networks. For example, congestion phenomena in multi-hop networks are very different than in traditional wired...
