There is provided mechanisms for making resources discoverable. A method is performed by a resource location mapping node. The method comprises acquiring scope information of a local network and location information enabling determination of specific locations of resources in the local network. The method comprises generating Constrained Application Protocol (CoAP) resource identifiers of the resources from the scope information and the location information. The method comprises providing the CoAP resource identifiers to a resource directory, thereby making the resources discoverable.

Discovery of resources in a local network

A method and a mesh node () for enabling communication of packets in a wireless mesh network with multiple mesh nodes. When receiving () an original advertisement message with a Bloom filter initiated by an original gateway (), it is detected that a predetermined maximum fill rate is reached in the received Bloom filter. The mesh node () starts to act as an intermediate gateway and creates a new advertisement message () comprising a new initiated Bloom filter with a reduced fill rate. The new advertisement message is then transmitted () with the new Bloom filter while indicating that the new advertisement message originates from said original gateway ().

There is provided mechanisms for handling acknowledgements from nodes in a wireless radio ad-hoc network. A method is performed by a gateway of the wireless radio ad-hoc network. The method comprises transmitting radio signalling to nodes in the wireless radio ad-hoc network. The transmitted radio signalling is addressed to, and requiring acknowledgement from, at least one node in the wireless radio ad-hoc network. The method comprises receiving radio signalling from a node in the wireless radio ad-hoc network. The received radio signalling comprises one in-packet Bloom Filter comprising acknowledgement of the transmitted radio signalling from at least one of the nodes.

A method performed in a client device for setting up a connection with a server device is disclosed. The client device and the server device support a Light Weight Machine to Machine, LWM2M protocol. The method comprises setting up one of a Datagram Transport Layer Security, DTLS, and a Transport Layer Security, TLS, connection with a bootstrap server; performing a bootstrapping procedure with the bootstrap server; receiving, from the bootstrap server, a session ticket and a session key; and setting up the connection to the server device as one of a DTLS and TLS session resumption procedure using the received session ticket and session key. A method in a bootstrap server is also provided, and client device, bootstrap server, computer programs and computer program products are also disclosed.
