cooperative.rar - An ad-hoc network with a sender, a destination and a third station act- ing as a relay is analysed. The channels are modelled containing thermal noise, Rayleigh fading and path loss. Di® erent combining methods and di- versity protocols are compared. The amplify and forward protocol shows a better performance than the decode and forward protocol, unless an error correcting code is simulated. To combine the incoming signals the chan- nel quality should be estimated as well as possible. Information about the average quality shows nice bene¯ ts, and a rough approximation about the variation of the channel quality increases the performance even more.
function-TDSR.rar - Ad-hoc networks refer to temporary networks which form for special purposes. Mobile ad-hoc networks (MANETs) are networks which use no network assisting element for routing, but every node has the role of router and actively participates in data forwarding. Security problems in MANETs are specified and investigated separately, because in these infrastructureless networks, in addition to all available problems in a wired or wireless network, there are some more problems. Since all connections are available in wireless form and they are audible, so they can be changeable. Also nodes themselves are involved in routing, so existence of a malicious node can lead to the destruction of the network and one of the most important challenges in these networks
wsn-simulation-in-matlab.rar - Wireless Sensor Networks (WSN) is different than the Cellular Networks as I mentioned earlier. A WSN is composed of a large number of sensor nodes that communicate using a wireless medium (air). The sensor nodes are deployed randomly in the environment to be monitored. The sensor nodes distributed in ad hoc structure. In WSN there is no base station and not all nodes hear each other. The WSN is a multi-hop network. Basic part of my code is to randomly place the sensor nodes in the given space then connecting each two nodes if the distance between them less than or equal to the communication radius.
ALOHA.rar - 基于时隙式ALOHA无线自组织网络MATLAB代码,有载波侦听,信噪比模型 - 车载自组织网络中路边性能及防碰撞算法研究Research on the performance and anti collision algorithm of the vehicular ad hoc network - Energy consumption is a significant issue in ad hoc networks since mobile nodes are battery powered. In order to prolong the lifetime of ad hoc networks, it is the most critical issue to minimize the energy consumption of nodes. In this paper, we propose an energy efficient multipath routing protocol for choosing energy efficient path. This system also considers transmission power of nodes and residual energy as energy metrics in order to maximize the network lifetime and to reduce energy consumption of mobile nodes. The objective of our proposed system is to find an optimal route based on two energy metrics while choosing a route to transfer data packets. This system is implemented by using NS-2.34. Simulation results show that the proposed routing protocol with transmission power and residual energy control mode can extend the life-span of network and can achieve higher performance when compared to traditional ad-hoc on-demand multipath distance vector (AOMDV) routing protocol - MANET ad hoc Network
7213211Dijkstra_router.rar - Abstract—We propose two novel energy-aware routing algorithms for wireless ad hoc networks, called reliable minimum energy cost routing (RMECR) and reliable minimum energy routing (RMER). RMECR addresses three important requirements of ad hoc networks: energy-efficiency, reliability, and prolonging network lifetime. It considers the energy consumption and the remaining battery energy of nodes as well as quality of links to find energy-efficient and reliable routes that increase the operational lifetime of the network. RMER, on the other hand, is
