Mobile nodes in a mobile ad hoc network communicate with each other. In order to facilitate communication of mobile nodes with fixed nodes in the Internet, gateways are used. The resultant integrated heterogeneous architecture is called Integrated Internet MANET in the literature. Such heterogeneous architectures are needed in order to realize the potential of, and to achieve the stated objectives of proposed 5G networks of the future. Gateways in Integrated Internet-MANET may be fixed or mobile. Several issues arise in Integrated Internet-MANET. In this paper, three critical issues encountered in Integrated Internet-MANET are addressed together. These issues are, efficient gateway selection mechanism, adjusting the gateway advertisement range and dynamically adapting the periodicity of gateway advertisements. Three strategies are proposed which use a path load balancing mechanism for efficient gateway selection. These strategies address the issues of adjusting the gateway advertisement range and dynamically adapting the periodicity of gateway advertisements in different ways. The proposed strategies have been simulated in a two-tier as well as a hybrid architecture using network simulation tool ns-2. The simulation results are presented and the scenarios, under which each of the proposed strategies is useful, are discussed.

“…In [12], the authors take into account the traffic load along a path in addition to using a minimum hop count to select an efficient gateway selection. [13][14][15][16] propose to use the traffic load infor-mation of the gateway as the metric for gateway selection. In [17], the authors propose a gateway and route selection scheme for backbone WMNs that takes the gateway load, route interference, and path quality metric into account.…”

Abstract-In Wireless Mesh Networks (WMNs), we usually deploy multiple Internet Gateways (IGWs) to improve the capacity of WMNs. As most of the traffic is oriented towards the Internet and may not be distributed evenly among different IGWs, some IGWs may suffer from bottleneck problem. To solve the IGW bottleneck problem, we propose an efficient scheme to balance the load among different IGWs within a WMN. Our proposed load-balancing scheme consists of two parts: a traffic load calculation module and a traffic load migration algorithm. The IGW can judge whether the congestion has occurred or will occur by using a linear smoothing forecasting method. When the IGW detects that the congestion has occurred or will occur, it will firstly select another available IGW that has the lightest traffic load as the secondary IGW and then inform some mesh routers (MPs) which have been selected by using the Knapsack Algorithm to change to the secondary IGW. The MPs can return to their primary IGW by using a regression algorithm. Our Qualnet 5.0 experiment results show that our proposed scheme gives up to 18% end-to-end delay improvement compared with the existing schemes.

“…al. [8], the length of the routing queue in addition to minimum hop count metric is used for the selection of gateway by the mobile node. This approach has been extended by updating the path to the gateway on the request of mobile node which facilitates efficient handoff from one gateway to another, and thus maintaining continuous connectivity to the fixed host.…”

The Integration of the MANETs and infrastructure networks such as Internet, known as heterogeneous network, extends the network coverage and increases the application domain of the MANET. Communication between a mobile device in an ad hoc network and a fixed device on the Internet is achieved using gateways, which acts as a bridge between them. The ad hoc routing protocol AODV is extended and used to achieve interconnection between a MANET and the Internet. In the existing approaches of gateway discovery either interface queue length or the minimum hop metric criteria or a combination is used for selecting the gateway by the mobile nodes. In the proposed approach, an efficient proactive gateway discovery algorithm is devised that takes into account the length of the routing queue in addition to the minimum hop count metric for selecting an efficient gateway and also selecting the routes to other mobile nodes. This is a novel strategy of gateway discovery. This approach is implemented by calculating the load along a path and updating the routing entry as the route requests are processed from one mobile node to the other. This allows usage of updated routes without waiting for the gateway advertisements for updating the routing entries. It also reduces the delay along the path for the packets traversing within the ad hoc network. The use of this concept increases the throughput by choosing the less congested paths and reduces the routing overhead. In this paper the impact of this new approach is investigated. Simulation results indicate that our protocol outperforms other approaches.
