RPL was projected as an
answer for routing in low-power and lossy networks (LLNs) and catered to distinctive routing challenges.
LLNs area unit usually resource affected in terms of memory,
battery life and process power.
They embrace Wireless
Personal space Networks
(WPANs), low-power transmission
line Communication networks (PLC) and Wireless sensing element Net-works
(WSNs). normal routing
protocols like OSPF weren’t fitted to the special challenges that LLNs exhibit. RPL was specially
designed to beat these
challenges. It enclosed several specific options like dynamic rate of management message dispatch supported network consistency and addressing topology
changes only if knowledge packets have to be compelled to be sent. Attributable to such style concerns, RPL was ready
to stay conservative
in terms of affected resources.
However, the RPL feature set enclosed repetitions
of tasks already performed by alternative IP layers. It additionally enclosed several inessential options that were formed in real deployments.
Consequently, the specification proved a
lot of too complicated to
implement in completeness on one resource affected node.
Due to this, several current implementations of RPL solely implement a set of the initial feature-set, creating them
non-interoperable. so as to
be standards-compliant and thereby practical, it’s needed that the implementations embrace a particular set
of options, that isn’t continually doable given the scale and memory limitations
of the nodes in operation in
LLNs. to boot, the under specification
and ambiguity within the standards
document make to an oversized variety of implementation selections, several of that adversely impact overall
This thesis analyses the shortcomings of RPL,
and additionally proposes a brand new routing
protocol that might probably function a typical designed of
RPL with less quality and
a reduced feature-set.
Internet of Things (IoT) may be a paradigm that’s more and more growing within
the context of pervasive networks and services.
It consists within the extension of the
web to things from the physical world, that are
interacting with one another so as to
succeed in common goals in several application
1. The high interest for this paradigm has
resulted within the large-scale readying of
Low power and lossy Networks (LLN), like
wireless detector networks and
residential automation systems.
2. These networks suffer from scarce resources
and unreliable links. As an endeavor to
standardize protocols employed in the IoT, a
fanatical stack has been designed having
in mind of the constraints. specifically for the
routing layer, the IETF
RoLL2 unit has planned a whole new protocol known as RPL
(Routing Protocol for Low
power and lossy Networks) supported IPv6 and
specially designed for net of Things
3. we’ve an inclination to propose during
this thesis to deal
with security observance problems concerning the
RPL routing protocol within
the context of IoT networks. Indeed, the
multiple constraints long-faced by these
networks create them notably at risk of security
4.Addressing security in such environments may
be a real challenge considering all
their limitations. Therefore, the planned
solutions ought to be as light-
weight as potential so as to attain the simplest
trade-off between security and
its induced price for the network.
5.This introduction provides the context
and conjointly the
analysis queries of this thesis.
First, we’ve an inclination to
Internet of Things paradigm and conjointly the
power and lossy networks with their routing necessities. we’ve an inclination to then
detail the challenges of this new paradigm and
additional specially the problems self-
addressed during this thesis
