In this paper the application spectrum of wireless ad hoc network is a typical battle field monitoring system for the public safety purpose and military sector where the sensor network simulator architecture is used to provide support for sensing capabilities in network nodes for different mobility conditions. Rayleigh and Rician fading (K=3) model is used for the effect of channel fading in the network scenario. The channel fading incurs extra network overhead in the PHY, MAC and Network layer. A comprehensive study on the performance of ad hoc network routing protocols under realistic network scenarios with the effect of channel fading models is presented.

Optimal Node

This article considers a problem to choose parameters of a procedure for changing node roles in a multi-gateway wireless ad hoc network used in aerospace systems. Mathematical formulation of a mixed-integer programming (MIP) model to optimize the changing-node-role-procedure parameters is proposed, where the attention is focused on appropriate parameterization in order to make it possible to include additional constraints, if necessary. A practical two-stage technique used by the authors to solve the considered problem is briey discussed. On the first stage, the branch-and-bound algorithm, provided with cutting plane constraints of some classes, is applied to choose optimal roles of the network nodes. On the second stage, the network simulator developed by the authors is used to estimate main characteristics of the resulting network. Workability of the proposed approach is demonstrated by results of computational experiments.

Vehicular Ad-hoc Network (VANET), a subset of Mobile Ad-hoc networks (MANETs), is one of the emerging technologies of Road Transportation system. In recent years, the aspect of Vehicular Ad-hoc Network (VANET) is becoming an interesting research area as it is characterized as self-configured wireless network. The design of routing protocols in VANETs is play a vital role and necessary issue for the Vehicle to Vehicle Communication Technology. The existing routing protocols of MANETs are suitable for VANET with changes in configuration of protocol. The routing protocols fall into two major categories of topology-based and position-based routing. We discussed different kinds of existing routing protocols with two major categories, the advantages and limitations of each which will helps to enhance the existing routing protocols for the suitability of Vehicular Ad-hoc Networks. We implemented three existing routing protocols and the testing results stated that the performance of each in aspects of various parameters such as Packet Delivery Ratio, Throughput and End-End Delay using Network Simulator.
