Rakesh Kumar Saini, Ritika Ritika · International Journal of Advanced Science and Technology · 2017
In Wireless Sensor Network, Sensors nodes have limited power and resources.Sensor nodes are used for monitoring particular area in wireless sensor network.Due to lack of limited resources, a sensor node does not work properly with traditional layered routing protocol.Traditional layered routing protocol allows interaction between wireless protocol stack layers adjacently but does not allow interaction between wireless protocol stack layers non-adjacently.Cross layer design approach can allow interaction between wireless protocol stack layers non-adjacently.Cross layer design approach allows sharing variables between layers.Developing cross layer design approach is most important for improve Quality of Service (QoS) parameters like Energy-efficiency, throughput and Average end to end delay in Wireless Sensor Networks.Thus our focus is to improve the Quality of Service (QoS) for Wireless Sensor Network.One of the ways to improve Quality of Service (QoS) is cross layer design approach.In this paper we propose a cross layer design approach (IQOS) which optimizes Quality of Service (QoS) factors of the sensor nodes at the Network Layer, Data Link Layer and Physical Layers of the wireless protocol stack because Quality of Service (QoS) factors exist in these three layers.
