Data delivery of packets in broad cast using wireless medium is the main intention of this paper, this will be done through a MANETS and should achieve reliable delivery. To do this various protocols are available in the networks world with in that efficient protocol called Position based opportunistic routing protocol which holds stateless property of geographic routing. When a data packet is ...

In this paper, we proposed a photonic packet switching control method by used optical correlator for optical packet label packetswitched networks for next Generation networks. The main advance is rely on using the Optical Code Division Multiplexing (OCDM) code to labeling optical packets based on source routing. Based on OCDM labeling either header modification or any label swapping techniques ...

Reducing number of forwarding nodes is the main focus of any broadcasting algorithm designed for ad-hoc wireless networks. All reliable broadcasting techniques can be broadly classified under proactive and reactive approaches. In proactive approach, a node selects a subset of its neighbors as forwarding node and announces the forwarding node list in the packet header during broadcast. On the ot...

Routing in ad-hoc sensor networks is a complicated task because of many reasons. The nodes are low powered and they cannot maintain routing tables large enough for well-known routing protocols. Because of that, greedy forwarding at intermediate nodes is desirable in ad-hoc networks. Also, for traffic engineering, multipath capabilities are important. So, it is desirable to define routes at the ...

Protocol comparison: Performance of TORA was compared to Ideal Link-State (ILS) and pure flooding. Since TORA often provides multiple downstream routes, a next-hop forwarding decision is required. Two different forwarding policies were evaluated: TORA for each packet randomly(based on uniform distribution) select one of the downstream neighbors to forward the packet to, and TORA LN forward all ...

Node Location information may reduce the overall communication overhead for packet forwarding in Mobile Ad-Hoc Networks (MANETs). This paper proposes a novel Geographic Location Aware Adaptive Routing (GLAAR) protocol to reduce the computation and communication requirement for selection of next node (hop) for packet forwarding. Proposed protocol fetches the node location information using GPS a...

In this paper, we propose a pointer forwarding scheme with mobility-aware binding update in Hierarchical Mobile IPv6 networks. In the proposed scheme, a pointer chain between access routers (ARs) is established to reduce the binding update (BU) traffic to the mobility anchor point (MAP). In addition, the MN performs a binding update to the correspondent node (CN) depending on its mobility. Spec...

ODMRP (On-Demand Multicast Routing Protocol) [5] [7] [1] is a popular multicast protocol for wireless ad hoc networks. The strengths of ODMRP are simplicity, high packet delivery ratio, and non-dependency on a specific unicast protocol. ODMRP floods a route request over the entire network to select a set of forwarding nodes for packet delivery. However, a single forwarding path is vulnerable to...

In this paper we describe an XML-based platform for dynamic active node policy updates. XML supports the definition of specific policy languages, their extension to satisfy new needs and the management of deployed policies on different active nodes. We show an example of the management of router packet forwarding policies where the XML policies that drive the packet routing are updated at run-t...
