—This survey guides the reader through the extensive open literature that is covering the family of low-density paritycheck (LDPC) codes and their rateless relatives. In doing so...
Sensor networks with battery-powered nodes can seldom simultaneously meet the design goals of lifetime, cost, sensing reliability and sensing and transmission coverage. Energy-har...
Abstract—We provide an overview of link scheduling algorithms in Spatial Time Division Access (STDMA) wireless mesh networks. These algorithms can be classified into three categ...
Abstract—Exchanging cryptographic keys to encrypt the media stream in the Session Initiation Protocol (SIP) has proven difficult. The challenge is to effectively exchange keys w...
Abstract—The computational and memory resources of wireless sensor nodes are typically very limited, as the employed low-energy microcontrollers provide only hardware support for...
