Nodes in wireless multi-hop networks establish links with their neighbors, which are used for data transmission. In general, in this kind of networks every node has the possibility of acting as a router, forwarding the received packets when they are not the final destination of the carried data. Due to the routing protocol procedures, when the network is(More)
In this paper, a new mechanism for topology control in wireless mesh networks is proposed. We evaluate the application to this problem of the centrality metrics developed by social network analysts. Our target network is a wireless mesh network created by user hand-held devices. For this kind of networks, we aim to construct a connected dominating set that(More)
Many proposals have studied the optimization of the EDCA mechanism used by the IEEE 802.11p MAC layer to provide QoS. In this work, we focus on the queuing process done by the different Access Categories (ACs). We propose the use of a single common buffer with a prioritized buffer allocation algorithm inspired on the MAX-MIN principle for a fair sharing of(More)
This paper proposes a mixed linear and integer optimization model for multi-hop ad-hoc networks to select the positions of the gateways over a certain area. This model mimics the routing behavior of such network and takes into account the maximum bandwidth capacity of the network gateways. We also include a suboptimal solution for the cases in which the(More)
