چکیده
we study the problem of transmission-side diversityand routing in a static wireless network. In this paper, we present a new medium access control (MAC) protocol forad-hoc networks with multiple input multiple output (MIMO) links. Instead of using perfect synchronizationtechnique, we assume the cooperative transmission is asynchronous. It is shown that the energy savings of 39% and 56% areachievable in line and grid networks with a large number of nodes, respectively.This paper describes theassumptions, the implementation process and the challenges wewere presented with.The MAC protocol proposed in addresses thisissue using an efficient cooperative scheme. Ageneral decision feedback equalizer (DFE) is used in the receiving cluster members to equalize the received MISO signal and detect as soft symbols. The receiving cluster members send the soft decision outputs to the destination node.Up to 80% in energysavings can be achieved for a grid topology, while for random nodeplacement our cooperative protocol can save up to 40% in energyconsumption relative to the other protocols.

Power Allocation Strategies in Block-Fading Two-Way Relay Networks
This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...
متن کاملTraffic-and-resource-aware intrusion detection in wireless mesh networks
As the interest in Wireless Mesh Networks (WMN), as an infrastructureless wireless network, grows, security issues, especially intrusion detection, become of paramount importance. The diversity in hardware along with a variety of WMN applications, have resulted in WMN with different network characteristics (e.g., resource levels, system and security models, etc.). Consequently, different intrus...
متن کاملVIGOR+: Energy-Efficient Local Visibility Graph-based Geographic Routing in Large-Scale Sensor Networks
Geographic routing is well suited for point-to-point communication in large-scale wireless sensor networks, because it is a stateless protocol that is, the per-node state is independent of network size. However, the local minimum caused mainly by network holes makes the path stretch increase by up to O(c), where c is the optimal path length. Recently, Tan et. al. proposed a visibility graph-bas...

This study was conducted to quantitatively evaluate selfed (S1, S2 and S3) and open pollinated (OP1, OP2 and OP3) generations of alfalfa in terms of inbreeding depression and general combining ability of S2 families of alfalfa ecotypes. Selfing of selected plants to produce three generations of S1, S2 and S3 generations were performed under the field conditions and the clones of each selfed- ge...
متن کاملGOAL: A parsimonious geographic routing protocol for large scale sensor networks
Geographic routing is well suited for large scale sensor networks, because its per node state is independent of the network size. However, due to the local minimum caused by holes/obstacles, the path stretch of geographic routing may degrade up to O(c2), where c is the path length of the optimal route. Recently, a geographic routing protocol based on the visibility graph (VIGOR) showed that a c...
