Abstract
Problem statement: This study presents a source based reactive protocol called "Energy Aware Multiple Constraints QoS Routing Protocol with Dynamic Mobility Prediction (EMQRPDM)" for MANET. It is an enhanced version of our previous protocol called "Power aware multiple QoS constraints routing protocol with mobility prediction (PMQRPMP)". It addresses the issues such as routing, mobility and power management in MANET. Approach: EMQRPDM considers quality of service parameters namely delay, jitter, bandwidth and cost of each link on 'n' available paths and selects a stable optimal path between a source and a destination during path discovery. It checks a bandwidth constraint during route request. It also checks the energy level constraints for each node during route reply. EMQRPDM uses our new mobility prediction mechanism to determine the stability of link expiration time for each link of each path during route reply. It executes path maintenance procedure when the link between two nodes cuts off. It also considers a backup path during link failure. Results: EMQRPDM is compared with PMQRPMP. Even though the mobility speed of mobile nodes is increased to 10 m sec−1, the success rate of data transmission in EMQRPDM is 74% which is still higher than PMQRPMP. During link failure using a backup path, the cost of control overhead in EMQRPDM is 0.272 which is lower than PMQRPMP when the number of mobile nodes is increased from 15-40. Conclusion/Recommendations: EMQRPDM selects an optimal path with good battery backup using energy level constraints. It selects a best stable optimal path using our new mobility prediction mechanism. EMQRPDM gives better Packet Delivery Ratio. It reduces the cost of control overhead using the bandwidth constraint and a backup path. It can be further enhanced as a reliable, secure, hybrid and multicast communication protocol for MANET.
Highlights
This agreement is made based on the serviceMobile Ad hoc Networks (MANETs) can be defined as the infrastructure less, self coordinated, metrics namely end-to-end delay, jitter, bandwidth and cost while transporting a data packet from a source node to destination node (Murad and Al-Mahadeen, suddenly created wireless networks with a set of mobile 2007).nodes
These metrics were compared with the other metrics namely mobility speed and the number of mobile nodes
In EMQRPDM due to the use of new mobility prediction formula and energy level constraints, the cost of control overhead is 0.255 which is lesser than the values 0.27, 0.27 and 0.3 for PMQRPMP, MQRPMP and Ticket-Based Probing (TBP) respectively when the number of mobile nodes is 15
Summary
Mobile Ad hoc Networks (MANETs) can be defined as the infrastructure less, self coordinated, metrics namely end-to-end delay, jitter, bandwidth and cost while transporting a data packet from a source node to destination node (Murad and Al-Mahadeen, suddenly created wireless networks with a set of mobile 2007). Some of main issues in MANET metrics They can be classified as time constraints, are routing, mobility management, reliability, power consumption and security. J. Computer Sci., 7 (6): 892-901, 2011 routing is to find a feasible path through the network mobility prediction mechanism which finds LET and between the source and destination that will have the predicts the stability of LET based on dynamic mobility necessary resources available to meet the QoS of nodes for finding an optimal path between two constraints (Murad and Al-Mahadeen, 2007).
