The primary contribution of the WAdL design is the ability to maintain, despite the mobility of the participating devices, a virtual lattice where the devices represent lattice points.
Multi-hop wireless networks, such as sensor-, ad hoc- and mesh-nets, can be differentiated in terms of participating devices and usage scenarios.
Along with this service, the opportunistic networking service of Cocoon facilitates fast and reliable information sharing between participating devices according to our real-world applicability and validation experiments presented in this work.
The space extent of composite device can be calculated by all the space extents of participated devices, i.e., σ { ( x cds 1, y cds 1, z cds 1 ), …, ( x cdsm, y cdsm, z cdsm ) } = Ω ( σ { ( x d 11, y d 11, z d 11 ), …, ( x d 1 m, y d 1 m, z d 1 m ) }, …, σ { ( x dk 1, y dk 1, z dk 1 ), …, ( x dkm, y dkm, z dkm ) } ) (25).
The composite device ability refers to all the participated device abilities in spatial extent.
The space extent of composite device operation can be calculated by all the space extents of participated device operations, i.e., σ { ( x comOp 1, y comOp 1, z comOp 1 ), …, ( x comOpm, y comOpm, z comOpm ) } = Ω ( σ { ( x op 11, y op 11, z op 11 ), …, ( x op 1 m, y op 1 m, z op 1 m ) },, … σ { ( x opk 1, y opk 1, z opk 1 ), …, ( x opkm, y opkm, z opkm ) } ) (22).
First, there is a lack of incentives for the participating wireless devices to serve as relay nodes.
Resilience: A blockchain does not have a single point of failure (SPOF), as with centralized data management, because all information is shared equally among the participating mobile devices.
Transparency: A blockchain transparently opens all the resource status and usage data by default because it shares the resource metadata with all the participating mobile devices.
AnonySense allows applications to submit sensing tasks to be distributed across participating mobile devices, later receiving verified, yet anonymized, sensor data reports back from the field, thus providing the first secure implementation of this participatory sensing model.
In this paper, the Secure Authentication Management human-centric Scheme (SAMS) is proposed, which uses blockchain to authenticate mobile devices and trust the resource information in the mobile devices participating in the MRM resource pool.
