“…To maintain scalability in these heterogeneous ad hoc networks (capacity of a network to maintain its performance when the number of nodes increases) hierarchical routing protocols ( Figure 2) should be considered as a good option [11], [12], [13]. On the other hand, if the objective of the MANET is offering realtime services -such as video streaming-it will be interesting to evaluate the performance offered by the routing protocols.…”

“…The basic principle in our hierarchical OLSR approach is similar to the CRC HOLSR described in [12] and [13] but there are several differences. In our proposal, we consider that there are only two levels in the hierarchy, where level-1 corresponds to connection among type-1 nodes (core network) and level-2 corresponds to connection among type-2 nodes (access network) ( Figure 3).…”

A performance evaluation of real time services (such as video streaming) over mobile ad-hoc networks using both hierarchical and flat routing protocols is showed in this paper. A variety of workload and scenarios, as characterized by mobility, load and size of the ad hoc network have been simulated using NS-2. We use OLSR as the flat routing protocol and our own implementation of HOLSR (which uses HNA messages) as the hierarchical one. We make a complete comparison between these protocols focused on video evaluation. The simulations lets us compare the quality of service (QoS) of the video streaming paying attention to objective parameters (PSNR, packet delivery ratio, packet delay). Results indicate that traffic overload is reduced and video quality is improved using hierarchical protocols.

“…It has been found that this strategy improves routing discovery and reduces effect of route failure. In [14], scalability issue of OLSR in heterogeneous MANET has been studied. The study show that OLSR it does not differentiate distinct nodes with different communication capability and resources.…”

“…The common approach to dealing with heterogeneity of nodes in previous papers [13][14][15] is to assign most of the routing load for the powerful nodes, as they possess more resources and communication capabilities. Consequently, this approach eliminates number of hopes and can reduce delay.…”

Abstract-In Mobile Ad hoc Network (MANET), mobility, traffic and node density are main network conditions that significantly affect the performance of routing protocols. Much of the previous researches in MANET routing have focused on developing strategies, which suit one specific networking scenario. Therefore, there is no existing protocol that can work well in all different networking scenarios. This paper reviews characteristics of each different classes of routing protocols. Moreover, most of current routing protocols assume homogeneous networking conditions where all nodes have the same capabilities and resources. Although homogenous networks are easy to model and analysis, they exhibits poor scalability compared with heterogeneous networks that consist of different nodes with different resources. This paper presents extensive studies simulations for DSR, AODV, LAR1, FSR and WRP in homogenous and heterogeneous networks. The results showed that these which all protocols perform reasonably well in homogenous networking conditions, their performance suffer significantly over heterogonous networks.

“…Yang et al proposed contention-aware admission control for MANT in [8]. The Hierarchical Optimized Link Routing (HOLSR) [10] is based on the protocol specifications for the OLSR [9] algorithm. HOLSR dynamically organizes nodes into cluster levels, and these clusters are organized into a hierarchical architecture.…”

Most routing protocols focus on obtaining a workable route without considering network traffic condition for a mobile ad hoc network (MANET). Therefore, the quality of service (QoS) is not easily achieved by the real time or multimedia applications. To support QoS, this work proposes a QoS-aware routing protocol that incorporates an admission control scheme into route discovery and route setup. A dual-card dual-signal mechanism is adopted to increase system performance. Simulation results show the proposed protocol can more significantly improve packet delivery ratio, throughput (in heavy load), as well as reduce average end-to-end delay than routing protocols without QoS support can.
