|6.5.2 Comparative Analysis
SMDDP provides a simple and powerful way for the semantic discovery of ambient intelligent medical devices in pervasive (healthcare) environments, utilizing and exploiting the advantages of HTTP protocol. Although, several discovery mechanisms for pervasive computing have been proposed in the past, but none of them is widely adopted. Edwards has published a comparative study  about SSDP, Jini, Bluetooth SDP, SLP, Bonjour, Salutation, INS and Ninja SSDS, including also infrared and RFID mechanisms. The comparison was based on different parameters, i.e. topology, transport, scope, search and security.
Table 6.1 shows a reproduction of the Edwards' comparison table with the additional row of SMDDP, which exhibits some distinct factors by comparing it with other alternatives, such as its powerful semantic discovery capabilities and the use of widely-adopted and reliable HTTP-based security mechanisms. This comparison shows and promotes SMDDP to be the best candidate for the semantic discovery of ambient intelligent medical devices in pervasive computing scenarios within the healthcare domain, and also a valuable and promising alternative in other networking environments as well.

|3.8 Comparative analysis
mRDP provides a simple and powerful way for performing semantic queries in Ubiquitous Computing environments, taking advantage and reusing HTTP infrastructure. Several discovery mechanisms for Ubiquitous Computing have been proposed in the past, none of them widely accepted. Edwards published a comparative [Edw06] about SSDP, Jini, Bluetooth SDP, SLP, Bonjour, Salutation, INS and Ninja SSDS, including also infrared and RFID mechanisms. The comparison was based on the criteria of topology, transport, scope, search and security.
We reproduce in Table 3.1 the comparison table with an additional row for mRDP5.
mRDP exhibits some distinct factors from other alternatives, such as its powerful semantic search capabilities, and the use of well-proven and reliable HTTP-based security infrastructure.
We deem mRDP to be the best candidate for intelligent discovery in pervasive computing scenarios, and also a valuable and promising alternative in other networking environments.
5 The rows for eSquirt (infrared) and RFID are not included, since they are not relevant for the current research.
