Simulated analysis of connectivity issues for sleeping sensor nodes in the internet of things

The growth in wireless sensor network deployments requires a move towards more standardised systems to improve compatibility and to reduce development times. The technologies being developed as part of the Internet of Things, such as 6LoWPAN (IPv6 over Low power Wireless Personal Area Networks), can greatly assist with this aim. Connecting low power wireless sensor network devices to the Internet of Things presents certain challenges. One of these challenges is the lack of constant connectivity to sensor nodes with sleep states. Current internet technologies expect that devices are always contactable which is not the case in sensor networks.
