“…In prior work [19], we demonstrated that network-layer performance is highly dependent on how many and which terminals are included in the backbone network. In particular, we showed that minimizing the number of terminals in the backbone leads to poor performance for some small networks.…”

Efficient routing in mobile ad hoc networks (MANETs) is highly desired and connected dominating sets (CDS) have been gaining significant popularity in this regard. The CDS based approach reduces the search for a minimum cost path between a source and destination terminals to the set of terminals forming the backbone network. Researchers over the years have developed numerous distributed and localized algorithms for constructing CDSs which minimize the number of terminals forming the backbone or which provide multiple source-destination paths between each pair of terminals. However none of this research focuses on minimizing the load at the bottleneck terminal of the backbone network constructed by the CDS algorithms. A terminal becomes a bottleneck if the offered traffic load is greater than its effective transmission rate. In this paper we analyze the load based performance of a CDS algorithm and a k-connected k-dominating set (k-CDS) algorithm and compare it with our centralized algorithm which has been designed to minimize the load at the bottleneck terminals of the backbone network. We verify the effectiveness of our algorithm by simulating a large number of random test networks.

Abstract-Group communication over multicast ad hoc network suffers from insufficient utilization of limited resources, i.e. shared channel, battery, data processing capabilities and storage space etc. Multicast routing protocol should be able to manage all these resources because their consumption depends upon different factors, i.e. Unicast/Multicast network operations, dynamic topology due to mobility, control overhead due to scalability, packet loss and retransmission due to collision and congestion etc. All these factors may cause unnecessary network load, delay and unfair resource utilization. However, multicast ad hoc routing protocols are more efficient than Unicast routing protocols, but they also suffer from performance degradation factors discussed above. Researchers have developed various layer wise solutions for resource optimization. In this paper, we will explore the different schemes for fair utilization of network resources.

“…Available bandwidth information can be used as a routing metric to select forwarding path(s) that can offer better end-to-end available bandwidth. Proposed framework can be used to support realtime multimedia applications for IEEE 802.155.4 based networks.Jackson.C.A et al[12] proposed a hierarchical and heterogeneous multichannel ad hoc network. The channels employed by this network are non-overlapping, and each channel differs significantly in its characteristics, such as achievable data rate, communication range, and traffic load.…”

Researchers have developed various layer wise solutions for resource optimization. In this paper, we will explore the different schemes for fair utilization of network resources and also perform a simulation based analysis to investigate the impact of MAC layer over the performance of multicast routing protocols and network resources.
