A derivative of AODV, denoted LOADng, is proposed for use in very constrained environment, sacrificing a number of features from AODV for the benefit of smaller control messages and simpler processing logic. Among these sacrifices is intermediate route replies. This…

Data delivery across a multi-hop low-power and lossy networks (LLNs) is a challenging task: devices participating in such a network have strictly limited computational power and storage, and the communication channels are of low capacity, time-varying and with high loss…

This specification describes an extension to the Optimized Link State Routing Protocol version 2 (OLSRv2) to support multiple routing topologies, while retaining interoperability with OLSRv2 routers that do not implement this extension. This specification updates RFCs 7188 and 7631 by…

Jitter is a small, random variation of timing before message emission that is widely used in non-synchronized wireless communication. It is employed to avoid collisions caused by simultaneous transmissions by adjacent nodes over the same channel. In reactive (on-demand) routing…

Jittering (a small, random variation in timing of control message emission) is widely used in protocols for wireless communication, in order to avoid simultaneous packet transmis- sions over the same channel by adjacent nodes in the network. Used for both…

Solutions for mobile ad hoc routing have matured over the last decade. Building atop these foundations, new challenges are set for MANETs, such as integration in the Internet core. On this topic, this paper designs and evaluates MPR-OSPF, an extension…

Heterogeneous networks combining both wired and wireless components – fixed routers as well as mobile routers – emerge as wireless mesh networks are being deployed. Such heterogeneity is bound to become more and more present in the near future as…

This paper analyses the impact of jitter when applied to route discovery in reactive (on-demand) routing protocols. In multi-hop non-synchronized wireless networks, jitter—a small, random variation in the timing of message emission—is commonly employed, as a means to avoid collisions…

Many protocols for Mobile Ad-hoc Networks propose construction of routes reactively using flooding. The advantage hereof is that no prior assumption of the network topology is required in order to provide routing between any pair of nodes in the network….

This paper proposes an extension to the “LLN On-demand Ad hoc Distance-vector Routing Protocol – Next Generation” (LOADng), for efficient construction of a collection tree for data acquisition in sensor networks. The extension uses the mechanisms from LOADng, imposes minimal…

Introduction The Lightweight On-demand Ad hoc Distance-vector Routing Protocol –Â Next Generation (LOADng) is a routing protocol, derived from AODVÂ and extended for use in Mobile Ad hoc NETworks (MANETs) and Low-power and Lossy Networks (LLNs). The LOADng control messages are carried…
