Abstract
The Mobile Adhoc Network (MANET) support in anywhere and anytime wireless communication expands the multimedia applications’ scope. Ever demanding task of multimedia applications to determine the quality of routers among huge number of portable devices is to improve Quality of Service (QoS). To support real time multimedia streams, several geographical based QoS routing protocols have been proposed; however, the portable devices’ expansion leads to stringent QoS demands in MANET. The main reason behind the QoS demand is the dynamic network capacity which relies on network size, node mobility, density, node energy, and communication range. The existing protocols are inefficient to the delay sensitive multimedia applications over MANET due to the lack of attention on dynamic network capacity. This work presents a new Network Capacity based Geographical routing (NCG) along with several routing schemes such as Radio Range Regulation (RRR) routing, Virtual Destination Routing (VDR), and Virtual Void Routing (VVR) called NCG++. is called NCG++. The NCG++ routing estimates the network capacity in terms of QoS, facilitating minimum energy for every node to provide the QoS for varying network size, node mobility, and node density. Finally, this work simulates and compares the proposed NCG++ routing protocols performance with the existing QoS-GPSR. Thus, the performance evaluation illustrates that the NCG++ routing protocol outperforms the existing protocols.
