In this work, the concept of network coding (NC) is used in conjunction with the routing and spectrum allocation (RSA) problem to jointly provide security and protection in elastic optical networks (EONs). Specifically, to provide security against eavesdropping attacks, a number of XOR operations are performed at specific network nodes using already established connections, enabling the confidential connections to transmit an encrypted version of their data. In order to protect and maintain the security of the confidential connections in the event of any single link failure, a protection mechanism is further proposed, enabling the receiver at the destination nodes to decode the signals during normal network operation as well as network operation under fault conditions. NC-based RSA algorithms are proposed for different classes of demands and their efficiency is examined in terms of spectrum utilization, network blocking, and the level of security they provide.

In this paper we address the problem of resource allocation for alarm traffic in industrial Internet of Things networks using massive MIMO. We formulate the general problem of how to allocate pilot signals to alarm traffic such that delivery is guaranteed, while also minimising the number of pilots reserved for alarms, thus maximising the channel resources available for other traffic, such as industrial control traffic. We present an algorithm that fulfils these requirements, and evaluate its performance both analytically and through a simulation study. For realistic alarm traffic characteristics, on average our algorithm can deliver alarms within two time slots (of duration equal to the 5G transmission time interval) using fewer than 1.5 pilots per slot, and even in the worst case it uses around 3.5 pilots in any given slot, with delivery guaranteed in an average of approximately four slots.
