TL;DR: This paper proposes two mobility-aware clustering algorithms that take into consideration the mobility properties of users in order to improve the WMN performance and proposes a new interference-aware routing metric, called INX, for this purpose.

TL;DR: Security analysis and performance evaluation show that SEAODV is more effective in preventing identified routing attacks and outperforms ARAN and SAODV in terms of computation cost and route acquisition latency.
Abstract: This paper describes a Security Enhanced AODV routing protocol for wireless mesh networks (SEAODV) SEAODV employs Blom's key pre-distribution scheme to compute the pairwise transient key (PTK) through the flooding of enhanced HELLO message and subsequently uses the established PTK to distribute the group transient key (GTK) PTK and GTK are used for authenticating unicast and broadcast routing messages respectively In wireless mesh networks, a unique PTK is shared by each pair of nodes, while GTK is shared secretly between the node and all its one-hop neighbors A message authentication code (MAC) is attached as the extension to the original AODV routing message to guarantee the message's authenticity and integrity in a hop-by-hop fashion Security analysis and performance evaluation show that SEAODV is more effective in preventing identified routing attacks and outperforms ARAN and SAODV in terms of computation cost and route acquisition latency

TL;DR: This investigation shows that for a wide class of network settings, POC-based design allows more flexibility in wireless resource allocation, and can improve overall network capacity by as much as 100%.
Abstract: Partially overlapped channel (POC) based design, has been identified recently as a promising technique to overcome the capacity bottleneck facing wireless engineers in various networks, such as WLAN, wireless mesh network (WMN) and ad hoc networks. However, considerable confusions still exist as to the actual power of POCs to improve network capacity, especially since traditional communication system designs treat the so called adjacent channel interference (ACI) as harmful. Based on measurements of actual testbed experiments, we model the impact of POCs on system design and use numerical method to analyze network capacity improvement comparing POC-based design and traditional design. Our investigation shows that for a wide class of network settings, POC-based design allows more flexibility in wireless resource allocation, and can improve overall network capacity by as much as 100%.

TL;DR: This study shows how localized self-configuration mechanisms can impact the global network behavior with respect to node degree, robustness, channel quality, data aggregation and latency.
Abstract: The basic topology desired in data-gathering wireless sensor networks is a spanning tree, since the traffic is mainly in the form of many-to-one flows. Nodes in the network can self-configure themselves into such a topology by a two-phase process: a flood initiated by the root node, followed by parent selection by all nodes. We present four localized topology generation mechanisms - earliest-first, randomized, nearest-first, and weighted-randomized parent selection. We also compare the network performance of these mechanisms on the basis of the following metrics: node degree, robustness, channel quality, data aggregation and latency; our study shows how localized self-configuration mechanisms can impact the global network behavior.

TL;DR: In this paper, a radio-based wireless mesh packet network is considered, where packet traffic is scheduled between a high capacity communications link and a plurality of nodes interconnected by wireless links, and an access unit is provided at a first node having a plurality radio coupled to the high capacity link and wherein each of the plurality of radios is capable of detecting a polling of the access unit by other nodes.
Abstract: In a radio based wireless mesh packet network wherein packet traffic is scheduled between a high capacity communications link and a plurality of nodes interconnected by wireless links, an access unit is provided at a first node having a plurality of radios coupled to the high capacity link and wherein each of the plurality of radios is capable of detecting a polling of the access unit by other nodes. A poll is sent from a second node to the access unit at the first node on a first channel. Reports of receipt of the poll are shared among the plurality of radios. An acknowledgment is sent on behalf of the access unit from only one of the plurality of radios to the polling node, and further communication is conducted between the one of the plurality of radios and the node on a second channel.
