Reliability and Trust in Mobile Ad-hoc NETworks (MANET) are considerable due to their applicability in different situations such as military‚ emergency applications or health care applications. Indeed‚ due to absence of a fixed infrastructure and a central controller‚ providing trust and reliability still is challenge in these networks. Since energy is limited and distributed in MANETs‚ trust and reliability providing (is different from wired systems and it must be reasonable and compatible with

3. PATH LOSS MODELS Path loss models play a vital role in planning of wireless communication systems. They represent a set of mathematical equations and algorithms that are used for radio signal propagation prediction in certain areas. Propagation path loss models are used for calculation of electromagnetic field strength for the purpose of wireless network planning during preliminary deployment. Path loss model describes the signal attenuation from transmitter to receiver antenna as a function of

The matrix elements are complex numbers that correspond to the attenuation and phase shift that the wireless communication channel introduces to the signal reaching the receiver with delay τ. 3.1.1 Benefits of MIMO Systems 3.1.1.1 Interference reduction and avoidance Interference in wireless networks results from multiple users sharing time and frequency resources scheme. Interference may be mitigated in MIMO systems by exploiting the spatial dimension to increase the separation among users. Interference

this technique to solve a huge menace in our country and that is traffic management. Wireless sensor networks will be set up in the vehicles on board communication unit in order to collect real time data on traffic and road conditions‚ traffic control‚ and real-time traffic re-routing by intelligent traffic management systems. In this paper unique features and challenges that distinguish the wireless sensor system from other traffic management systems are also discussed. One more important application

pister} @Ieecs. berkeley.edu Abstract Large-scale networks of wireless sensors are becoming an active topic of research. Advances in hardware technology and engineering design have led to dramatic reductions in size‚ power consumption and cost for digital circuitry‚ wireless communications and Micro ElectroMechanical Systems (MEMS). This has enabled very compact‚ autonomous and mobile nodes‚ each containing one or more sensors‚ computation and communication capabilities‚ and a power supply. The

Analysis of a Stochastic Model for Wireless Sensor Networks Submitted By: Syed Ahsan Ali Bokhari Introduction:Our aim is to develop a stochastic model of sensor networks where each sensor node is taken randomly and one after the other in sleep and active state. After analysis of the sensor model‚ we try to formulate the probability when there are many data packets in many sensor nodes. The model is analyzed in terms of energy usage‚ delay in average data and efficiency. With the increasing
