Paper: Evaluation of routing protocol for low power and Lossy Networks: LOADng and RPL

Routing protocol is a critical component of Low-power and Lossy Networks for Smart Grid. The protocols are used for data forwarding, which includes data acquisition, information dissemination, etc. This paper evaluates two main routing protocols used for Low-power and Lossy…

Internship Opening: Light, Efficient Multicast with B.I.E.R.

Light, Efficient Multicast with B.I.E.R. B.I.E.R. (Bit-Indexed Explicit Replication) is a multicast mechanism wherein the source of the multicast data packet (i.e. the ingress router which injects the multicast data packet into a B.I.E.R. domain) explicitly identifies and indicates (by…

Internship Opening: Aggregate Signatures for Mutable Messages

Aggregate Signatures for Mutable Messages Many protocols rely on generation, exchange and processing of mutable messages, i.e., they base their correct functioning on the recipient of a control message “trusting” that the originator of the message, as well as any…

LOADng – The Lightweight On-demand Ad hoc Distance vector routing protocol, Next Generation

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

LoRa: Ubiquitous connectivity for the IoT?

LoRa (as developed by the LoRa Alliance) is a long-range, low-power, low-bitrate, wireless telecommunications system, promoted as an infrastructure solution for the Internet of Things: end-devices use LoRa across a single wireless hop to communicate to gateway(s), connected to the Internet…

The Routing Standard for Dynamic, Wireless, Ad hoc, MESH networks: OLSRv2

With the recent publication of RFC7939, I wrote in a previous blog entry that: This is, to some extend, the final piece of the core OLSRv2 (the Optimized Link State Routing Protocol version 2) puzzle – which is also therefore the…

RFC7939 – the final piece to the OLSRv2 puzzle

OLSR Logo

RFC7939 has just recently been approved: and published. This is, to some extend, the final piece of the core OLSRv2 (the Optimized Link State Routing Protocol version 2) puzzle – which is also therefore the final piece of a 10+ years adventure of…
