Mobile ad hoc networks consist of freely moving nodes responsible of not only forwarding packets for other nodes but can also perform extensive computations. One of the most critical issues in these networks is the significant differences in term of processing and energy capacity between the nodes, inducing a load imbalance. Thus, sharing the load between the overloaded and idle nodes is a necessity in ad hoc networks. In this paper, we present a new load balancing algorithm based on clustering where a subset of nodes 'clusterheads' is elected to maintain some balance within their respective clusters while minimizing the overall communication cost. Our primary goal is to minimize the total execution time of the tasks by distributing the workload among nodes. Another goal is to extend the overloaded nodes lifetime inducing a stability of the network. The simulation results have shown that network performance can be reached by distributing load to idle nodes within the network.

“…Related works: Differential Services (DiffServ) (Zarifzadeh et al, 2007) is a computer networking architecture that specifies a simple and scalable mechanism for classifying, managing network traffic and providing QoS guarantees on modern IP networks; however in the competition of DiffServ and MPLS, MPLS has been emerging as the protocol of the NGN for many reasons such as that MPLS is a multi protocol technology, where it can work over ATM, FR, etc. Also, MPLS is capable of providing controllable QoS features (Urra et al, 2006) by utilizing Classification, Queue and Scheduling (CQS) which enables high quality end-to-end service features that are necessary in applications such as VPN (Chung et al, 2001).…”

Problem statement: Traditional IP networks have many limitations such as routing tables, which can be complex and time consuming. These limitations affect the performance of the network in some applications of triple play services (i.e., voice, video and data) which are characterized as time sensitive applications. Thus, Multi Protocol Label Switching (MPLS) technology has been proposed to speed up the traffic flow in the network using labels. Approach: In this study, an experiment using the Network Simulator NS-2 was performed to evaluate the impact of MPLS technology on the Triple Play Services based on the average throughput of the network, total number of packets received at destination nodes and packet loss rates and this is compared to that provided by traditional IP networks. Results: The results showed that MPLS performs better since it utilizes all the available paths to the destinations. Conclusion: MPLS allows Internet Services Providers (ISPs) to provide better triple play services for end-users
