The congestion and queue delay are the critical problems that may face the heterogeneous networks, because of the huge data broadcasting in every network segment.So the selection of suitable strategy to solve these two major problems is considered in this work.Therefore, this paper proposes two new strategies based on optimized link state routing protocol (OLSR), random early detection (RED) and weight random early detection (WRED), which we defined them as OLRED and OLWRED respectively.These two proposed strategies are applied and examined the performance of the heterogeneous networks in terms of three important metrics: throughput, utilization and queue delay.Our simulation results are done using OPNET and they show that the proposed strategies are improved the QoS for the heterogeneous networks and reducing the congestion with high network productivity.
