چکیده

1 Summary Network scalability is one of the critical challenges and requirements in routing protocols for ad hoc networks. This paper presents a novel scalable routing protocol called Geo-LANMAR. The proposed protocol inherits the group motion support of Landmark Routing (LANMAR) and applies the geo-routing concept to deliver packets efficiently. In this framework, the integration between geo-coordinates and table-driven IP addressing is introduced. There is also an integration of group management with geo-forwarding and IP group management. Geo-LANMAR uses link-state propagation over a virtual topology built on landmarks, and a Fisheye like scheme makes this propagation very efficient. The virtual topology helps recover from voids. For extra efficiency, a novel metric called Effective Traveled Distance (ETD) allows us to predict voids or obstacles. With respect to LANMAR, Geo-LANMAR reduces advertisement update overhead and features robust forwarding. Consequently, Geo-LANMAR is more scalable to large ad hoc networks with group motion. The performance evaluation of Geo-LANMAR shows that Geo-LANMAR gives high scalability for large networks in terms of control overhead, end-to-end delay, and packet delivery ratio as compared with other routing protocols such as AODV, LANMAR and GPSR.

Multiple-Landmark Routing for Large Groups in Ad Hoc Networks

A typical scenario in Mobile Ad Hoc Networks (MANET) consists of nodes having functional and motorial affinities (e.g., tanks in the same battalion). In order to achieve scalability for such a network having a large scale, we introduce, in this paper, a novel ”Multiple-Landmark” Ad Hoc Routing protocol (M-LANMAR). The protocol is an ”implicit”, flexible hierarchical routing scheme following the...

Dynamic group support in LANMAR routing ad hoc networks

In Mobile Ad Hoc Networks (MANETs) mobile nodes are often organized in groups with different tasks and, correspondingly, different functional and operational characteristics. In particular, nodes in the same group will have coordinated motion. The coordinated motion pattern considerably simplifies the mobility management and allows efficient and scalable routing. Such a mobile network can easil...

Scalable Team Multicast in Wireless Ad hoc Networks Exploiting Coordinated Motion

In this paper, we study a new multicast paradigm for large scale mobile ad hoc networks, namely team multicast. In team multicast the multicast group does not consist of individuals, rather, of member teams. For example a team may be a special task force that is part of a search and rescue operation. The message must be broadcast to each member of each team in the multicast group. Team multicas...

Landmark routing for large ad hoc wireless networks

In this paper, we present an enhanced version of the routing protocol Landmark Ad Hoc Routing (LANMAR). LANMAR combines the features of Fisheye State Routing (FSR) and Landmark routing. The enhanced version features landmark election to cope with the dynamic and mobile environment. Other advantages of LANMAR include the use of landmarks for each logical group (e.g., a team of co-workers at a co...

"Direction" Forwarding for Highly Mobile, Large Scale Ad Hoc Networks

In this paper, we present a novel packet forwarding scheme for wireless ad hoc networks --“Direction” Forwarding (DFR). Popular routing protocols such as DSDV and AODV use “predecessor” based forwarding, namely, the packet is forwarded to the predecessor on the shortest path from the destination, as advertised during the last update. Predecessor forwarding may fail in large scale networks where...
