A Constrained Application Protocol (CoAP) Usage
for REsource LOcation And Discovery (RELOAD)
Abstract
This document defines a Constrained Application Protocol (CoAP) Usage
for REsource LOcation And Discovery (RELOAD). The CoAP Usage
provides the functionality to federate Wireless Sensor Networks
(WSNs) in a peer-to-peer fashion. The CoAP Usage for RELOAD allows
CoAP nodes to store resources in a RELOAD peer-to-peer overlay,
provides a lookup service, and enables the use of RELOAD overlay as a
cache for sensor data. This functionality is implemented in the
RELOAD overlay itself, without the use of centralized servers. The
RELOAD AppAttach method is used to establish a direct connection
between nodes through which CoAP messages are exchanged.
