  Information Centric Networking is a new networking paradigm that treats
content as first class entity. It provides content to users without regards to
the current location of the content. The publish/subscribe systems have gained
popularity in Internet. Pub/sub systems dismisses the need for users to request
every content of their interest. Instead, the content is supplied to interested
users (subscribers) as and when it is published. CCN/NDN are popular ICN
proposals widely accepted in the ICN community however, they do not provide an
efficient pub/sub mechanism. COPSS enhances CCN/NDN with an efficient pub/sub
capability. Internet of Things (IoT) is a growing topic of interest in both
Academia and Industry. The current designs for IoT relies on IP. However, the
IoT devices are constrained in their available resources and IP is heavy for
their operation.We observed that IoT's are information centric in nature and
hence ICN is a more suitable candidate to support IoT environments. Although
NDN and COPSS work well for the Internet, their current full fledged
implementations cannot be used by the resource constrained IoT devices.
CCN-lite is a light weight, inter-operable version of the CCNx protocol for
supporting the IoT devices. However, CCN-lite like its ancestors lacks the
support for an efficient pub/sub mechanism. In this paper, we developed
COPSS-lite, an efficient and light weight implementation of pub/sub for IoT.
COPSS-lite is developed to enhance CCN-lite and also support multi-hop
connection by incorporating the famous RPL protocol for low power and lossy
networks. We provide a preliminary evaluation to show proof of operability with
real world sensor devices in IoT lab. Our results show that COPSS-lite is
compact, operates on all platforms that support CCN-lite and we observe
significant performance benefits with COPSS-lite in IoT environments.
