    Cross-Layer Based Performance Optimization for Different Mobility and Traffic Scenarios in Adhoc Networks

    The self configuring dexterous autonomy of MANET imposes some network challenges constrained to traditional dynamic routing behavior. So as working with different mobility and traffic patterns with normal management schemes may lead some minor pitfalls to some important network performance parameters and hence can degrade the whole network performance. Here,...
