The Requirements and Benefits of Applied SOA for WSNs.

SOA Approach	The Requirements
SODA for Smart Environment [71]	Support the heterogeneity Performance measurement effect on latency. The overhead that is related to SOAP message process was small when compared to messages transmission
SOA Model for Sensor Networks [72]	Multi-gateway uses to solve the issue of congestion that generate by using one gateway Authentication user Data should be located near the users and filter data near to distention Ability to linked various protocols that can be used for WSN
WSNs Cloud User Interaction	NaaS requires the WSN supporting Service-Oriented software architecture Non-collaborative [74,75]
FSONA [79]	Interoperability between service Supports QoS and run time Integrated with other system Service abstraction and discovery
SYLPH [64]	The devices are not requiring any features as large memory to communicate with SYLPH Improves the system security and efficiency for care services
OGC-SWE standards (Web Service) [68,70]	SWE standard helps to discovery sensors data and the interoperability Supporting the data detection Data retrieval increase for WSN through remote control Provide user authorized SWE standard helps to discovery sensors data and the interoperability Supporting the data detection
ANDSF	Solved problem the overhead between access networks and the service registry Provide mechanism for updating network states information in real time and service description
Healthcare Approaches	Supports efficient information retrieval Achieve the desired QoS in WSNs Support the heterogeneous and asynchronous
Configuration Service [76]	Adaptation at Runtime Reduce cost
